Shown in Fig. 3 B, the intensity distributions (be scattered field) of part with Y polarised direction under all angles value (θ) of the high-frequency signal that goes out from these two microstrip reflection array antennas (microstrip reflection array antenna of existing microstrip reflection array antenna and the present invention's first preferred embodiment) reflections is roughly the same, and represent two microstrip reflection array antennas two curves (respectively with " ◇ " reach "-" represent) there is no significant difference.Because it is the high-frequency signal of tool Y direction polarization that horn antenna is emitted to the signal of the reflecting plate of these two microstrip reflection array antennas, no matter so this phenomenon demonstrates these two microstrip reflection array antennas under any angle value (θ), both co-polarization position standards (co-polarization level) are roughly the same.
But, be noted that, shown in Fig. 3 B the latter half, but there is not person's significant difference in the intensity distributions (be scattered field) of part with X polarised direction under all angles value (θ) of the high-frequency signal that reflects from these two microstrip reflection array antennas (microstrip reflection array antenna of existing microstrip reflection array antenna and the present invention's first preferred embodiment), article two, curve not only differs a lot of, and the curve of the microstrip reflection array antenna of the present invention's first preferred embodiment (with " zero " expression) and significantly be lower than existing microstrip reflection array antenna curve (with " * " expression).In addition, because it is the high-frequency signal of tool Y direction polarization that horn antenna is emitted to the signal of the reflecting plate of these two microstrip reflection array antennas, so no matter the accurate cross polarization position standard that under any angle value (θ), all significantly is lower than existing microstrip reflection array antenna in the cross polarization position of the microstrip reflection array antenna of the present invention's first preferred embodiment.
Fig. 4 shows that actual these the two kinds of antennas (microstrip reflection array antenna of existing microstrip reflection array antenna and the present invention's first preferred embodiment) that measure are aiming at online radiation gain value in the frequency range of 9GHz to 12GHz, that is relatively both are aiming at the result of online co-polarization gain (bore sightco-polarization gain) with cross polarization gain (cross-polarization gain), wherein, in this frequency range (9GHz to 12GHz) and since represent two curves that the online co-polarization of the aiming of these two microstrip reflection array antennas (microstrip reflection array antenna of existing microstrip reflection array antenna and the present invention's first preferred embodiment) gains (respectively with "
" reach "-" expression) in whole frequency range (9GHz to 12GHz) there is no significant difference, so that these two microstrip reflection array antennas aim at the gain of online co-polarization is roughly the same in (9GHz to 12GHz) in whole frequency range.
But, shown in Fig. 4 the latter half, represent two curves of the cross polarization gain of these two microstrip reflection array antennas (microstrip reflection array antenna of existing microstrip reflection array antenna and the present invention's first preferred embodiment) in whole frequency range (9GHz to 12GHz), then not have person's significant difference, article two, curve differs very big, the curve of the microstrip reflection array antenna of the present invention's first preferred embodiment (with " zero " expression) and significantly be lower than existing microstrip reflection array antenna curve (with " * " expression).Therefore, in (9GHz to 12GHz), the cross polarization of the microstrip reflection array antenna of the present invention's first preferred embodiment gain all significantly is lower than the cross polarization gain of existing microstrip reflection array antenna in whole frequency range.
Fig. 5 be these two kinds of antennas of the actual measurement microstrip reflection array antenna of the present invention's first preferred embodiment (the existing microstrip reflection array antenna with) under the frequency of 10.4GHz, co-polarization radiation pattern (co-polarization radiationpattern) that both are had on H plane (H-plane) and cross polarization radiation pattern (cross-polarization radiationpattern).As shown in Figure 5, under this frequency (10.4GHz) and since represent the co-polarization radiation pattern that is positioned at H plane of these two microstrip reflection array antennas (microstrip reflection array antenna of existing microstrip reflection array antenna and the present invention's first preferred embodiment) two curves (respectively with "-" reach "--" represent) under all angles value (θ), there is no significant difference.So, though these two microstrip reflection array antennas under any angle value (θ), the co-polarization radiation pattern that is positioned at H plane is roughly the same.
But, shown in Fig. 5 the latter half, the cross polarization radiation pattern that is positioned at H plane of representing these two microstrip reflection array antennas (microstrip reflection array antenna of existing microstrip reflection array antenna and the present invention's first preferred embodiment) is next there are differences of all angles value (θ), and the curve of the microstrip reflection array antenna of the present invention's first preferred embodiment (with " ● " expression) be lower than existing microstrip reflection array antenna curve (with " zero " expression).Therefore, in this frequency (10.4GHz), and though the microstrip reflection array antenna of the present invention's first preferred embodiment be positioned at that H plane cross polarization radiation pattern all significantly is lower than existing microstrip reflection array antenna under any angle value (θ) be positioned at H plane cross polarization radiation pattern.
On the other hand, except second diameter of the ring of each microband antenna unit institute tool of making the reflecting plate upper surface that is positioned at microstrip reflection array antenna was 0.6 times of ratio of first diameter of outer shroud of same microband antenna unit institute tool, ratio between the two (length of second diameter is divided by the length of first diameter) also can be any numerical value between 0.4 to 0.8.But, when this ratio changes, the cross polarization position standard of this microstrip reflection array antenna also can with change.Microstrip reflection array antenna with the present invention's first preferred embodiment is an example, and second diameter of its each microband antenna unit/first diameter ratio is 0.6, and its cross polarization position criterion is about 36dB.But, if second diameter/first diameter ratio of each microband antenna unit of the reflecting plate institute tool of each microstrip reflection array antenna is changed into 0.8, then the cross polarization position standard of this microstrip reflection array antenna just can fail and be 20dB, and promptly the received noise (has the signal of another polarised direction) of this microstrip reflection array antenna is bigger.
