Description

ELECTRONIC DEVICE WITH ANTENNA MOUNT

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application Serial No. 62/150,085, filed April 20, 2015, which is incorporated by reference herein in its entirety.

FIELD

[0002] The present principles relate generally to electronics and, more

particularly, to an electronic apparatus and antenna mounting arrangement within an electronic device.

BACKGROUND

[0003] Electronic devices such as set-top boxes are typically assembled apparatuses having a plurality of walls and other components. These other components can include printed circuit boards, heat sinks or heat spreader, wires, hard drives, smart card assemblies, and antennas. The plurality of walls and components make the assembly of these devices quite challenging in high volume manufacturing

environments. As such, there is a need to insure that the components are staged, mounted, and installed in a manner that is fast and safe for the components. Further, there is a need to insure that the components are inspectable and designed in a manner that makes their installation as reversible as possible for rework in the factory or in the field. [0004] As such, some devices such as the vertically oriented set top box disclosed in International Application No. PCT/US15/17791 filed on February 26, 2015 incorporate screwless attachment concepts to assemble the housings of the devices in such a way that the access to the devices in the field can be performed in a safe efficient manner by an authorized person without the need to undue screws. Such designs as in the above mentioned application make gaining access to the interior components of these devices more convenient and reduce excessive handling.

[0005] The casings of the vertically oriented set top boxes and gateway devices are relatively tall. The bases are generally narrow. With such a geometry, these designs present more challenges than the horizontally oriented set top boxes for screwless housing assembling. The reason is it is difficult to include a locking mechanism in these tall boxes that can extend from the top side to the bottom side of the boxes and yet still be able to house the plurality of necessary components which can include a plurality of antennas without interfering with the locking mechanism.

[0006] The need for a plurality of antennas in these vertically oriented set top boxes or gateway devices particularly presents a challenge. The problem is that in some designs up to 7 antennas are required, which means that additional wires must be used to connect the antennas to a circuit board and additional fixtures or antenna supports must be installed in the devices to support the antennas. Further, the antennas not only involve extra handling of the work product in the factory that place other components at risk and drive up manufacturing cost, but also these antennas have a propensity for electrostatic discharge in use. As such, designers must ensure that the antennas are adequately shielded in these devices which tend to be quite crowded. Thus, the need exists for an antenna mounting system that is commensurate with the screwless attachment concepts and yet do not pose the risk of electrostatic discharge to and from the antennas.

[0007] These and other drawbacks and disadvantages presented by vertically oriented electronic devices are addressed by the present principles, which are directed to a vertical electronic apparatus and associated printed circuits. However, it can be understood by those skilled in the art that the principles can be taken advantage of in horizontally oriented devices as well. SUMMARY

[0008] According to the present principles, an electronic device 200 is provided that comprises a plurality of vertically oriented walls 204, 206, 208, a plurality of antennas 602 among which at least one of the antennas is positioned adjacent to a first wall of the vertically oriented walls and at least one of the antennas is positioned adjacent to a second wall of the vertically oriented walls, and an antenna bracket 601 . The antenna bracket can be a closed polygonal structure having at least two sides 603 that support the antennas. The antenna bracket can include a plurality of antenna pockets positioned on the at least two sides of the antenna bracket. Each of the antenna pockets can have an opening into which one of the antennas is inserted and supported in a vertical orientation. The antenna pockets can each have a top openings into which one of the antennas is inserted and a second opening from which the antenna wire of one of the antennas exits and is routed to one of a plurality of antenna connectors 606. The plurality of antenna connectors can be provided and positioned away from the antenna bracket. The antenna connectors can be configured to connect with a plurality of antenna wires 604 extending from each of the antennas. A printed circuit board 501 can be provided and positioned such that at least part of the printed circuit board is at a vertical height lower than the antenna bracket. The printed circuit board can further be configured such that the antenna connectors are positioned on a component side 504 of the printed circuit board. The printed circuit board can be vertically oriented and can be parallel to the first wall of the vertically oriented walls of the electronic device. The printed circuit board can further be configured such that the antenna connectors are positioned adjacent to a top edge of the printed circuit board. At least one of the antennas adjacent to the first wall has a plane that are laterally positioned between a plane of the first wall and a plane of the component side of the vertically oriented printed circuit board. Each of the antenna wires of the antennas can be routed to one of the sides of the antenna bracket and the antenna bracket can be mounted to the first wall by attaching one of the sides of the antenna bracket to the first wall. The electronic device can further comprise a housing having a lateral interior periphery defined by the interior surfaces of the vertically oriented walls such that the polygonal structure of the antenna bracket follows the lateral interior periphery.

[0009] According to the present principles, a vertically oriented set top box or a vertically oriented gateway device 200 is provided that comprises a plurality of vertically oriented walls 204, 206, 208, a plurality of antennas 602 among which at least one of the antennas is positioned adjacent to a first wall of the vertically oriented walls and at least one of the antennas is positioned adjacent to a second wall of the vertically oriented walls, and an antenna bracket 601 being a polygonal structure having at least two sides 603 that support the antennas. The set top box or device can include a housing having the vertically oriented walls, a top 210 and a base 205 opposite to the top such that one of the vertically oriented walls is a rear wall 206 that forms acute angles with respect to the other vertically oriented walls that extends from the rear wall. A lateral interior periphery can be defined by the interior surfaces of the vertically oriented walls such that the polygonal structure of the antenna bracket follows the lateral interior periphery and is adjacent to the top. A vertically oriented printed circuit board 501 can be mounted to the rear wall and a plurality of antenna connectors 606 configured to transmit antenna signal can be provided and positioned on the vertically oriented circuit board. Each of the antenna can have an antenna wire 604 extending from the antenna. The wires can be routed to and connected with one of the antenna connectors in which the antennas are vertically oriented. The vertically oriented printed circuit board can have a top edge that is positioned at a lateral position below lower edges of the antennas. The vertically oriented set top box or a vertically oriented gateway device can include a locking mechanism 214, 222 to engage the base to upper parts of the housing that includes the top. The locking mechanism can be screwless and located adjacent to the base. The antenna bracket can comprise a plurality of antenna pockets 605 that each has an opening into which one of the antennas is inserted and supported in a vertical orientation and a second opening from which the antenna wire of one of the antennas exits and is routed to one of the antenna connectors. The housing can be have a height that is larger than widths of each of the vertically oriented walls. The antennas can be positioned along the rear wall and two others of the vertically oriented walls. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF EMBODIMENTS

[0041] FIG. 1 shows a perspective view of a vertically oriented electronic device

200 that houses an antenna bracket 601 and antennas 602. The device can include a top 210, a front wall 208, a rear wall 206, side walls 204, and a base 205.

[0042] FIG. 2 shows the three principal pieces of the vertically oriented electronic device 200. The three pieces are the case bottom piece 213, the case top front piece 21 1 , and the case top back piece 212. The case top front piece 21 1 and the case top back piece 212 are upper parts of the device 200.

[0043] FIG. 3 is a perspective view of a retention clip 214 which can be optionally composed of metal and is utilized to engage and secure the case bottom piece 213 to the case top front piece 21 1 and/or the case top back piece 212. The retention clip 214 is positioned toward the bottom of the electronic device and is a key part of the locking mechanism applied on the electronic device. By having the retention clip 214 at the bottom, the antenna bracket 601 and the antennas 602 can be positioned at the other end of the electronic device; hence, the antenna bracket 601 (shown in FIG. 36 at the top end of the rear wall 206) and the antennas 602 do not interfere with locking and/or unlocking of the electronic device. Additionally, the use of the retention clip 214 in concert with other features to be described permits easy access to the antenna bracket 601 and the antennas 602 when needed. The retention clip 214 can be part of a screwless locking mechanism positioned adjacent to the base 205 of the electronic device and can be remote from the antennas in the antenna bracket 601 , especially when they are positioned adjacent to the top 210.

[0044] FIG. 4 shows how the case top front piece 21 1 is slid back onto the case top back piece 212 of the electronic device 200, and then up into retaining elements in order to lock the two pieces together such that internal electronic components can be housed therein when the assembly is finalized.

[0045] FIGs. 5-7 show the specific engagement mechanism 215, 216, 217 to which the current principles are applied. A protruding ledge 216 extends inwardly from the interior surface of one of the vertical walls of one of the pieces. The protruding ledge 216 includes a protrusion 215 that engages a protrusion receiving opening 217 on the case top front piece 21 1 . The protrusion receiving openings 217 are generally horizontal ledges that have upstanding peripheral walls to make a slot that can receive the protrusions 215. The slots can be oversized in the dimension that is perpendicular to the interior surfaces of the vertical walls from which the horizontal ledge extends, or the slots can be oversized along its long lateral axis. The slot can be narrow along the dimension parallel to the vertical walls or along the horizontal ledge's short lateral axis to snuggly fix the protrusions 215. The protruding ledge 216, the protrusions 215, and the protrusion receiving openings 217 form a screwless engagement structure 977. The arrangement of the protruding ledges 216 and the protrusions 215 can be spaced from the interior top surface of the case top 210 to permit the antenna bracket 601 and the antennas 602 to be positioned at a lateral level between the interior top surface of the case top 210 and the protruding ledges 216 and the protrusions 215. This permits the antenna bracket 601 and the antennas 602 from interfering with the locking and/or unlocking the pieces of the electronic device. FIGs. 8 and 9 show further perspective views of the retaining elements that are used to engage the case top front piece 21 1 with the case top back piece 212. FIG. 8 shows ribs 218 that are positioned above the protrusion receiving openings 217 and also extend inwardly from the interior surface of one of the vertical walls of the front piece 21 1 . The ribs 218 would interfere with the case rear retention element if an assembly start position is attempted that is too low. FIG. 9 shows that a chamfer 299 guides the case top 210 to an acceptable start location. Rib 218 prevents case front from starting in a position that is too low by preventing excessive case travel which can damage components.

[0046] FIG. 10 is a disassembled perspective view of the vertically oriented electronic device 200 showing the interior of the case top front piece 21 1 and the case top back piece 212 of the electronic device 200 to which the current principles are applied. The retention protrusions 291 , the retention openings 292, and the over travel prevention portions 293 are shown in FIG. 10.

[0047] FIG. 1 1 is a bottom perspective view of the vertically oriented electronic device 200 in which the case bottom piece 213 is not attached.

[0048] FIGs. 12-14 are various views of the retention clip 214 to which the current principles are applicable. The retention clip 214 can be optionally composed of metal. The views show that the case top front piece 21 1 and the case top back piece 212 can be attached to one another and can then be attached to the case bottom piece 213 using the retention clips 214. The retention clips 214 are retained by elements on the case top front piece 21 1 and the case top back piece 212. The clip 214 is generally V- shape and includes an anchor portion 220 which is one side of the V-shape. The anchor portion 220 has a rectangular planar shape and has an aperture 277 that fits into an anchor base 221 of the case top front piece 21 1 and the case top back piece 212. FIG. 14 shows how the aperture 277 of the anchor portion 220 engages a protrusion 221 A in the anchor base 221 such that an inward pointing ledge at the top of the anchor portion 220 grasps a top portion of the anchor base 221 and a bottom inner wedge grasps the bottom portion of the anchor base 221 to secure the retention clip 214. This permits a locking portion 219 of the clip 214, which is the other side of the V-shape, to engage with elements of the case bottom piece 213 to close or assemble the electronic device 200. In particular, referring to Figs. 15-16, the top of the locking portion 219 can have a horizontal ledge that extends inwardly to contact a bottom surface of a clip engaging element 222. The locking portion 219 can further have an upward extension at the edge of the horizontal ledge to engage an edge of the bottom surface of the clip engaging element 222. As shown in 17, the outward spring force of the clip 214 causes the locking portion to move outward to engage the element 222. Although a V-shape is shown, a U-shape could be employed as well and both sides of the V or U-shape part can have different heights. The retention clip 214 and the engaging elements 222 can be part of a screwless locking mechanism positioned adjacent to the base 205 of the electronic device and can be remote from the antennas in the antenna bracket 601 which can be positioned adjacent to the top 210 of the electronic device.

[0049] FIG. 15 is a perspective view of the case bottom piece 213, which shows the base 205 and the clip engaging elements 222 that extend vertically upward from the bottom piece 213 to which the current principles are applied. The clip engaging elements 222 are designed to engage the locking portion 219 of the clips 214 on the case top front piece 21 1 and the case top back piece 212. A screwless clip and spring mechanism 288 is formed from the clips 214 and the clip engaging elements 222.

[0050] FIGs. 16 and 17 are perspective views showing how the case bottom piece 213 engages the case top front piece 21 1 and the case top back piece 212 to which the current principles are applied. Release finger 301 pushes the locking portion 219 inward to disengage the locking portion 219 as it enters an aperture 223.

[0051] FIG. 18 is a bottom perspective view of the vertically oriented electronic device 200 to which the current principles are applicable. The reason is that the apertures 223 for the unlocking are remote from the antenna bracket 601 and the antennas 602.

[0052] FIG. 19 is a view of a release fixture 300 to which the current principles are applied. FIGs. 16-19 show the release aperture 223 in base 205. A release finger 301 on a base of a release fixture 300 is permitted to enter the release aperture 223 to push the locking portion 219 inward toward the anchor portion 220, thereby removing the top portion of the locking portion 219 from the engaging element 222. This can be understood also with reference to FIG. 18 in which the release finger 301 (not shown in FIG. 18) will contact the outer edge of the locking portion 219 and move the locking portion 219 away from the engaging element 222.

[0053] FIG. 20 is a flow diagram showing an exemplary method 2100 for assembling an electronic device having a case bottom piece, a case top front piece, a case top back piece, an antenna bracket and antennas mounted therein. Here, at step 2105, the antenna bracket 601 is mounted onto an interior vertical wall of the case top front piece or case top back piece or mounted to a component that is mounted to the interior vertical wall of the case top front piece or case top back piece. At step 21 10, the case top front piece 21 1 is attached to the case top back piece 212 to form a top structure 210 using a screwless engagement structure 977. At step 2120, the top structure 210 is attached to the case bottom piece 213 using a plurality of screwless clip and spring mechanisms 288.

[0054] FIG. 21 is a flow diagram showing an exemplary method 2200 for disassembling an electronic device having a case bottom piece, a case top front piece, and a case top back piece having the antenna bracket 601 mounted therein . The method 2200 is applied to an assembled condition, wherein the case top front piece is attached to the case top back piece 212 to form a top structure 210 using a screwless engagement structure 977, and the top structure is attached to the case bottom piece using a plurality of screwless clip and spring mechanisms 288. At step 2210, a release fixture 300 is moved vertically upward to cause the release fingers 301 to also move vertically upward toward a bottom of the electronic device to simultaneously disengage a locking portion 219 of each of the plurality of screwless clip and spring mechanisms 288, thereby allowing the case top front piece 21 1 and the case top back piece 212 to be removed upward from the case bottom piece 213. At step 2220, the case top front piece 21 1 slides down with respect to the case top back piece 212 to disengage the screwless engagement structure 977 and separate the case top front piece 21 1 from the case top back piece 212 such that electronic components included within the electronic device can be accessed. [0055] The electronic device 200 can be a set-top box or the like and can be vertically oriented such that the height of the device is higher than the width of the front vertical surface and/or the rear vertical surface and/or the lateral depth. The lateral cross section can be a quadrilateral shape in which the front and back are parallel and the side surfaces are not parallel to one another. The device can be designed such that the release fixture and release fingers move vertically upward toward the bottom of the device to simultaneously disengage the plurality of the locking portions to allow the case top front piece 21 1 and the case top back piece 212 to be remove upward from the case bottom piece 213. The case top front piece 21 1 and the case top back piece 212 can then further be detached from one another by moving the case top in a motion oppose to that shown in FIG. 5 to attach the two pieces (case top front piece 21 1 and case top back piece 212). With the two pieces 21 1 and 212 attached, the assembly can be reassembled or assembled by aligning the clip engaging elements 222 with the clip 214 when the release fixture is removed or not present.

[0056] As noted above, the electronic device 200 can be a quadrilateral generally in which the front and back are parallel and the side surfaces are not parallel to one another. However, the general quadrilateral shape can include some additional vertical connecting surfaces to make at least two additional minor surfaces (i.e. substantially smaller vertical surfaces) 280 between the rear wall 206 and side walls 204 (as shown in Fig. 4).

[0057] Further disclosed is a method of making a printed circuit board to printed circuit board electrical connection or configuration 500 when a second printed circuit board 502 is positioned at a right angle to the primary printed circuit board 501 . This can include the second PCB being connected behind the primary PCB on the component side 504 and the second printed circuit board being positioned on a non-component or bottom side 505 of the primary PCB. The connection for the two PCBs is through connector 503.

[0058] FIGs. 22-25 show perspective views of circuit board assembly

configuration 500 which can be employed in the vertically oriented electronic device 200 to which the current principles are applied. The limited or small plan view cross-section area of the configuration 500 from the bottom view makes the configuration 500 commensurate with the screwless casing design of the vertically oriented electronic device 200. The reason is the plan view cross-section can effectively be a T-shape that can be positioned by design to avoid the screwless locking mechanism or vis-versa. Further, by having the antenna bracket 601 mounted in the finished product at heights in the device in which most of the antenna bracket 601 is above the top edge of the vertically oriented primary printed circuit board 501 makes the arrangement of the internal components further commensurate with the screwless casing design. With such an arrangement, the locking elements of the housing and the associated release fixture and release fingers for disassembly can be more freely positioned to avoid contacting or interfering with the printed circuit boards and/or other components. If one of the circuit boards were to be horizontally positioned, there would be less positions and greater constraints on the positioning of the locking elements of the housing and associated release fixture and release fingers. The circuit boards would need to be smaller and/or need to be positioned at higher locations with the device. [0059] Since a component side 504 of PCB 501 can face a rear wall 206 of the housing of the electronic device, a problem is that access to the components on the component side 504 and access to a secondary PCB 502 may need to be made through an undesirable cable. Cables add cost and a point of potential failure. However, the connector 503 in FIG. 23 provides a way for the secondary PCB 502 to be directly attached to the primary PCB 501 in which the secondary PCB 502 is inserted into the connector 503. This arrangement reduces cost, improves quality and makes assembly easier, with fewer possibilities for assembly error.

[0060] Because the PCB arrangement shown in FIGS. 22 and 23 reduces the number of cables, it makes room for the use of the plurality antenna cables or wires 604 needed to transmit antenna electrical signal within the device. As observed in FIG. 24, if the antenna connectors 606 are positioned near the top edge of the first printed circuit board 501 , it is possible to have the antenna connectors 606 on the component side 504. As such, the antenna wires 604 can be short and the overall number of

cables/wires within the device itself can be kept to a minimum number.

[0061] Also, having the connector 503 being elongated to run along the major axis adds stability to the support of second PCB 502 and such a configuration of the connector 503 being positioned in a central portion of the primary board 501 allows the second board 502 to fit more conveniently in the casing in which case top front piece 21 1 has a tapered shape in which the casing narrows to the front wall 208.

[0062] As shown in FIG. 25, in an embodiment, a portion of the second printed circuit board 502 includes an extension 591 of the second printed circuit board from a plane 592 that substantially abuts a surface of the second printed circuit board when the first printed circuit board 501 is connected to the second printed circuit board by the connector 503. Contacts 588 are arranged on the extension 591 .

[0063] FIG. 26 is a cross sectional perspective view of a circuit board assembly configuration 500 highlighting the connector 503 and showing the contacts 506 that are on the interior cavity 508 of the connector 503 to which the current principles are applied. The connector 503 can be a rectangular structure having peripheral walls 507. The rectangular structure can have a leading edge 510 that can be a flange that faces the component side 504 of the PCB 501 and contacts the PCB 501 and a portion of the connector 503 that protrudes through aperture 509 in the first PCB 501 . The connector 503 can extend back to the panel jack at the panel jack opening or can be connected to a cable running to the panel jack. The panel jack can be on the rear wall 206 of the electronic device or can be a part of the rear wall. The rear wall 206 can be part of the case top back piece 212 in which some of the lower rectangular features on the piece 212 in FIG. 1 1 can represent a panel jack.

[0064] FIGs. 27-28 show interior perspective views of the vertically oriented electronic device 200 illustrating the circuit board assembly configuration 500 to which the current principles are applied. These views show that the primary PCB 501 can be screwed, bolted, or secured to the rear case or the case top back piece 212.

[0065] The view in FIG. 28 further illustrates that the secondary PCB 502 can have a heat spreader or heat sink 512 on one of its sides. The heat spreader or heat sink 512 can have a central contact portion 513 that thermally contacts the PCB 502 or heat generating components thereon. The spreader or sink 512 can have a planar peripheral portion that permits heat to be radiated or convected away from the PCB 502. [0066] In an embodiment, the heat spreader or heat sink 512 can be generally parallel to the PCB 502 and both heat spreader or heat sink 512 and PCB 502 can be perpendicular to the PCB 501 . The heat spreader or heat sink 512 can further provide structural support for the second PCB 502. Here, the heat spreader or heat sink 512 can have a base edge with a vertical ledge 588 that connects to the first PCB 501 or the case back 212 to support by the heat spreader 512 and in turn the heat spreader 512 support the second PCB 502 through contact points 514 (which can be screws or bolts or the like). The contact points 514 can work in conjunction with connector 503 to support the PCB 502. The contact points can run along an edge of the PCB 502 opposite the edge of PCB 502 having the base edge (support edge). Other mechanical connection features 799, such as screws or bolts, can secure the main board 501 to the electronic device 200.

[0067] FIG. 29 shows an exemplary method 4800 for configuring multiple printed circuit boards in an electronic device 200 having a vertical orientation and having an antenna bracket, antennas, and an outer casing that includes a case bottom piece 213, a case top front piece 21 1 and a case top back piece 212 to which the current principles are applied. The multiple printed circuit boards include a first printed circuit board 501 and a second printed circuit board 502. Here, at step 4805, the antenna bracket 601 is mounted onto an interior vertical wall of the case top front piece or case top back piece or mounted to a component that is mounted to the interior vertical wall of the case top front piece or case top back piece. This mounting can include the use of screws, bolts or the like. At step 4810, a connector 503 is mounted to a first side of the first printed circuit board 501 . At step 4820, the second printed circuit board 502 is mounted to the first printed circuit board 501 in a perpendicular configuration 500 by the connector 503 on the first printed circuit board 501 , by passing a portion of the second printed circuit board 502 through a second side of the first printed circuit board 501 to engage the connector 503 on the first side of the printed circuit board 501 . The method can also include providing a structural support for a heat spreader or heat sink 512 having at least a portion thereof thermally contacting the second printed circuit board 502 or one or more heat generating components on the second printed circuit board 502, by connecting a vertical ledge of the heat spreader or heat sink 512 to the first printed circuit board 501 or to the case top back piece 212. At step 4830, a structural support is provided for a heat spreader or heat sink 512 having at least a portion thereof thermally contacting the second printed circuit board 502 or one or more heat generating components on the second printed circuit board 502, by connecting a vertical ledge of the heat spreader or heat sink 512 to the first printed circuit board 501 or to the case top back piece 212.

[0068] FIG. 30 shows the feature of the set top box without the case in which a plurality of antennas 602 are distributed over the printed circuit boards 501 and 502 and outside the peripheries of one or both of the orthogonally arranged printed circuit boards 501 and 502. An embodiment can include only one board and less than 7 antennas. Here, the first printed circuit board 501 with a board heat spreader and heat sink 520 (in which "board" refers to the heat sink or spreader being associated with the circuit board) is attached to one side of the first printed circuit board 501 that is opposite the side that connects to the second printed circuit board 502. The board heat spreader and heat sink 520 is between the first printed circuit board 501 and the rear wall 206 of the case top back piece 21 2 of the casing of the electronic device. The antennas 602 are connected to one of the circuit boards and, in this embodiment, are all attached to the first printed circuit board 501 . The antennas 602 can be connected to the antenna connector 606 on the first printed circuit board 501 by way of the antenna wires 604. The antennas can be WIFI antennas and can be vertically oriented in the vertically oriented set top box as shown and positioned adjacent to the top 21 0 between the outer top peripheral edges of the printed circuit boards and the top 21 0 of the set top box. The antennas positioned along the rear wall 206 can be parallel to the rear wall 206 and laterally positioned to be between a vertical plane extending from the plane of the first printed circuit board 501 and the rear wall 206. The antennas 602 can be laminated antenna printed circuit boards.

[0069] FIG. 31 A shows the rear wall 206 of the case top back piece 21 2 that is omitted in FIG. 30. FIG. 31 B shows the board heat spreader and/or heat sink 520 positioned adjacent to the rear wall, and FIG. 31 C shows the first printed circuit board 501 which is connected to the board heat spreader and/or heat sink 520 thereover.

[0070] Inspection of FIG. 30 shows that interior volume of vertically oriented electronic devices can be quite crowded with a complex arrangement of components that comprise circuit boards, the components on the circuit boards, and the components to which the circuit board components are physically or electronically connected. This crowdedness and complexity is further enhanced when a plurality of antennas is need, because the conventional arrangement of the antennas involves having its own independent support. This, in turn, adds to the number of interior components that must be individually staged, isolated from other components and installed. Further, in these vertically oriented electronic devices, it turns out that there are spatial constraints and inefficiencies with the individual supports. In other words, the need for rapid assembly in high volume factories makes it difficult to manufacture such devices in which the antennas are individually supported with their own supports.

[0071] In view of the above mentioned issues with individual supports and the need to shield antennas, a single unitary antenna bracket 601 is provided and shown in FIG. 32 for holding the plurality of the antennas 602 that were presented in FIG. 30. This perspective view shows the antenna bracket 601 that holds multiple antennas and antenna wires 604. The antenna bracket includes multiple bracket walls or sides 603 to form a polygon structure and antenna pockets 605 supported on at least two bracket walls, wherein the antennas fit within the pockets and the pockets prevent electrostatic discharge to and/or from the antennas. The antenna bracket 601 can have rounded corners and the sides 603, and the corners can follow or generally follow the interior contour of the vertical walls of the casing. FIG. 33 show a rear perspective view of the antenna bracket 601 in relation to the printed circuit board 501 .

[0072] FIG. 34 shows various perspective views of the antenna bracket 601 and how the antennas 602 slide into the pockets 605. In particular, the corner region 610 of the bracket 601 highlighted in FIG. 34A is enlarged in FIGs. 34B and 34C to show how the antenna 602 can be inserted into and supported by the pockets 605. The pockets 605 have a hollow structure with two broad walls parallel to the broad surfaces of the antenna and two openings. The pockets can further include two narrow opposing end walls that bridge the two broad walls. One opening can be at the top for the antenna to slide into and another opening at the bottom for the antenna wire 604 to extend through to connect preferably to one of the printed circuit boards.

[0073] FIG. 35 shows a perspective view of the antenna bracket 601 and how the antenna wires 604 can be routed to one bracket wall 603. This view along with the view in FIG. 30 shows that the antenna wires 604 can be routed from end of the antenna pockets 605 along the bracket walls 603 toward one of the bracket walls 603 and downward toward the antenna connector 606. Also, FIG. 35 and FIG. 34 show that the antenna bracket 601 can have mounting apertures 61 1 on at least one of its walls 603 to secure the bracket 601 to a wall of the housing of the electronic device or to a printed circuit board.

[0074] FIG. 36 shows a perspective view of the antenna bracket 601 and how the antenna wire 604 can be routed to one bracket wall 603 and down to the first printed circuit board 501 between the first printed circuit board 501 and the rear wall 206. The wires 604 can connect to connectors 606 at the edge of the first printed circuit board 501 . This view shows that the bracket 601 and the printed circuit board can both be attached to the same wall 206 of the housing of the device.

[0075] FIG. 37 shows a rear perspective view of the antenna bracket 601 and how the antenna wire 604 can be routed to one bracket wall 603 and down to the first printed circuit board 501 and connect to antenna connector 606 at the edge of the first printed circuit board 501 . This view shows that the bottom edge of the bracket wall 603 to which each of the wires 604 are routed can be separated from the top edge of the printed circuit board 501 to which the wires 604 are routed.
