Description

微带反射数组天线 Microstrip array antenna reflector

技术领域 FIELD

[0001] 本发明是关于一种微带反射数组天线,尤指一种具有较低的交叉极化位准(cross polarization level, XPL)的微带反射数组天线,以应用于卫星通讯的领域中。 [0001] The present invention relates to a microstrip antenna reflector array, especially one having a low level of cross-polarization (cross polarization level, XPL) micro-strip reflect array antenna to be applied to the field of satellite communications .

背景技术 Background technique

[0002] 在目前所使用的卫星通讯系统中(如卫星电视),由于大气层吸收或其它的原因, 实际可应用于信号传输的频率范围相当有限。 [0002] In the satellite communications system currently in use (such as satellite TV), since the atmosphere absorbs or other reasons, may be applied to the actual signal transmission frequency range rather limited. 但是,随着所需要传输的信号频道的数目大幅增加(如目前数百台的有线电视频道),传统利用不同频率来分别传输不同频道的方法(频率多任务)以不足以应付此一情况。 However, the number of signal channels with the need to transfer a substantial increase (as is currently hundreds of cable channels), traditional uses different frequencies to each transmission method different channels (frequency multitasking) insufficient to cope with this situation. 为此,目前除了频率多任务的方法以外,业界已使用一种利用具有不同极化方向的数个信号(具有相同频率)来分别传输不同频道的节目内容(极化多任务)。 For this purpose, in addition to the current frequency of the multitasking method, the industry has been used utilizing a plurality of signals having different polarization directions (having the same frequency) for transmission of different channels of programming content (multitasking polarization), respectively. 如此,卫星通讯系统可传输的节目频道便可大幅地增加,而无需发射新的通讯卫星上太空以扩充频道容量,节省下巨额的金钱。 Thus, the satellite communication system can transfer program channels can be greatly increased without the need to launch a new communications satellite in space to expand channel capacity, saving huge amounts of money down.

[0003] 但是,由于在同一个卫星通讯频率中,不同极化方向的信号分别代表不同节目频道的信号,所以如果卫星接收天线无法明确地辨别出所欲接收的信号的极化方向时,使用此一卫星接收天线的接收系统便可能同时接收到两个不同节目频道的信号(分别具有不同的极化方向)。 [0003] However, since a satellite communications in the same frequency, the signals of different polarization directions respectively represent signals of different program channels, so if the satellite receiving antenna is not clearly distinguish the desired direction of polarization of the received signal, this a receiving antenna of the satellite receiving system receives a signal while it may show two different channels (each having a different polarization directions). 如此,虽然所欲接收节目频道的信号强度较强,但另一节目频道(利用另一极化方向传输)的信号仍会造成如鬼影等的噪声,不利于收视。 Thus, although a desired program channel received signal strength of the stronger signal but another program channel (with another polarization direction of transport) will still cause a noise such as a ghost or the like, it is not conducive to viewing.

[0004] 图IA是现有的微带反射数组天线的示意图。 [0004] FIG IA is a schematic view of a conventional micro-strip reflect array antenna. 如图IA所示,现有的微带反射数组天线包括一接地板11、一反射板12、四个支撑单元13及一号角天线14。 As shown in FIG IA, the conventional micro-strip reflect array antenna comprises a ground plane 11, a reflector 12, four support unit 13, and a horn antenna 14. 其中,反射板12是通过由四个由绝缘材质构成的支撑单元13的支撑,而与由铜板构成的接地板11保持一特定距离。 Wherein the reflecting plate 12 is supported by the support unit consists of four 13 made of an insulating material, while maintaining a certain distance to the ground plate 11 by a copper plate. 此外,现有的微带反射数组天线在反射板12的上表面121布设有多个微带天线单元多个微带天线单元15,每一个微带天线单元15分别由一内环151与一外环152构成。 Further, the conventional micro-strip reflect array antenna 12 on the surface of the reflection plate 121 is laid with a plurality of microstrip antenna elements 15 a plurality of microstrip antenna elements, each microstrip antenna element 15 respectively, by an inner ring 151 and an outer ring 152 configuration. 另一方面,每一个微带天线单元15的尺寸(如外环152所具的第一直径的长度)是与其位于反射板12的上表面121的位置有关。 On the other hand, the size (e.g., length of the first outer ring 152 having a diameter) of each microstrip antenna element 15 is located in the reflecting plate 12 to its upper surface 121 of the relevant position. 此外,这些微带天线单元15更具有下列特征: In addition, the microstrip antenna element 15 further has the following characteristics:

[0005] 1.在同一个微带天线单元15中,内环151所具的第二直径的长度与外环152所具的第一直径的长度之间存在有一特定比例关系。 [0005] 1. In the same microstrip antenna elements 15, there is a proportional relationship between the particular diameter of the first length of the second length diameter of the inner ring 151 and outer ring 152 with the tool.

[0006] 2.在同一个微带天线单元15中,外环152与内环151均具有相同的宽度(4mm)。 [0006] 2. In the same microstrip antenna elements 15, the outer ring 152 and inner ring 151 have the same width (4mm).

[0007] 图IB是现有微带反射数组天线经过IE3D软件仿真所得到的平面波散射场的示意图。 [0007] FIG. IB is a schematic diagram of a conventional scattering field plane wave microstrip antenna array after reflection IE3D software simulation obtained. 从图IB中可以看出,现有的微带反射数组天线仍具有显著的交叉极化位准。 As can be seen in FIG. IB, the conventional micro-strip reflect array antenna still has a significant level of cross-polarization. 意即,当所欲接受的信号为Y极化方向的信号时,现有的微带反射数组天线仍会较本发明的微带反射数组天线相对而言接收到较强的X极化方向(具有相同频率)的信号,即前述的问题。 Which means, when the desired signal is received when the polarization direction of the signal Y, the conventional micro-strip reflect array will be smaller than the microstrip antenna reflector array antenna of the present invention is received relatively strong X direction of polarization (having the same frequency) signal, i.e., the foregoing problems.

[0008] 因此,业界亟需要一种只能接收到单一极化方向的高频信号(如节目频道信号) 的微带反射数组天线,即一种具有较低的交叉极化位准的微带反射数组天线,以提升卫星通讯系统的卫星接收天线的接收品质。 [0008] Accordingly, an urgent need exists to only one kind of a single direction of polarization of the received high-frequency signal (e.g., program channel signal) of micro-strip reflect array antenna, i.e., having a low level of cross-polarized microstrip reflective array antennas to improve the reception quality of the satellite receiving antenna of the satellite communications system. 发明内容 SUMMARY

[0009] 本发明目的是提供一种微带反射数组天线,是用以发射及接收一高频信号,其包括:一接地板;一具有一上表面的反射板,此上表面布设有多个微带天线单元,且每一此等微带天线单元具有一内环与一外环;多个支撑单元,此等支撑单元支撑此反射板于此接地板的上方,使此反射板与此接地板之间维持一特定距离;以及一信号发射单元,是位于反射板的上方,以发射及接收此高频信号;其中,每一此等微带天线单元的外环的尺寸是依据此外环位于此反射板的上表面的位置而定;每一此等微带天线单元的外环具有一第一直径, 每一此等微带天线单元的内环具有一第二直径,且同一微带天线单元的外环的第一直径与内环的第二直径之间存在有一第一比例关系;每一此等微带天线单元的外环挖设有至少一第一沟槽,每一此等微带天线单元的内环挖 [0009] The object of the present invention to provide a micro-strip reflect array antenna is used for transmitting and receiving a high frequency signal, comprising: a ground plate; a reflective plate having an upper surface, this upper surface has a plurality of laid microstrip antenna elements, and each of these microstrip antenna unit having an inner ring and an outer ring; a plurality of supporting units, such plate supporting unit supports the reflected thereto over a ground plate, so that the reflected with this contact plate maintaining a certain distance between the floor; and a signal transmission unit, it is located above the reflection plate to transmit and receive the high frequency signals; wherein each of these micro-strip antenna element is based on the size of the outer ring is located in addition the position of the upper surface of this reflector plate may be; each of these micro-strip antenna element having a first outer diameter, the inner ring of each of these microstrip antenna unit having a second diameter, and the same microstrip antenna exists between the second inner diameter and the outer diameter of the first unit has a first proportional relationship; each of these micro-strip antenna element provided with at least a first outer digging trenches, each of these micro inner band antenna unit digging 有至少一第二沟槽。 At least one second groove.

[0010] 因此,通过由在本发明的微带反射数组天线的每一微带天线单元的外环及内环挖设两个第一沟槽及两个第二沟槽(即两个第一沟槽的联机方向平行于两个第二沟槽的联机方向),当本发明的微带反射数组天线处于其「接收状态」时,本发明的微带反射数组天线可利用这些沟槽有效地隔绝其微带天线单元因一极化方向垂直于两个第一沟槽的联机方向的高频信号而产生的感应电流,使得本发明的微带反射数组天线仅能接收一极化方向平行于两个第一沟槽的联机方向的高频信号,大幅减低本发明的微带反射数组天线接收到一极化方向垂直于两个第一沟槽的联机方向的高频信号的机会,有效地降低其交叉极化位准。 [0010] Thus, by the outer ring and the inner ring of each microstrip antenna element microstrip antenna array according to the present invention, the reflection of the two first trenches dug trench and a second two (i.e. first two line parallel to the direction of the grooves of the second groove line direction of the two), when the micro-strip reflect array antenna of the present invention in which the "reception status" micro-strip reflect array antenna of the present invention can utilize effectively the grooves microstrip antenna element which is isolated due to a polarization direction perpendicular to the line direction of the two high-frequency signals of the first trench and the induced current, so that the micro-strip reflect array antenna of the present invention can receive only a polarization direction parallel to the two high-frequency signal line direction of the first trenches, the present invention substantially reduce microstrip array antenna receives a reflected direction of polarization perpendicular to the high frequency signal opportunity line direction of the two first trenches effectively reducing the cross-polarization level. 所以,通过由使用本发明的微带反射数组天线,卫星通讯系统便可以利用同一个频率同时传送两种或两种以上的信号(每一种信号均具有不同的极化方向),大幅提升卫星通讯系统的容量及信号的接收品质。 Therefore, two or more transmission signals reflected by the microstrip array antenna of the present invention, the satellite communication system can use the same frequency simultaneously (each signal having a different polarization directions), dramatically satellite the reception quality and capacity of communication system signals.

[0047] 经过仿真之后,现有的微带反射数组天线的平面波散射场(plane wavescattering field)如图IB所示,而本发明第一较佳实施例的微带反射数组天线的平面波散射场则如图3A所示。 [0047] After the simulation, (plane wavescattering field) shown in FIG. IB field plane wave scattering conventional micro-strip reflect array antenna, the microstrip antenna array reflecting a first preferred embodiment of the present invention, the scattering field plane wave As shown in FIG. 3A. 另外,为了比较方便两者之间的差异,图:3B是由图IB与图3A 合并而成。 Further, in order to facilitate the difference between the two, FIG: 3B is formed and FIG. IB merger FIG. 3A.

[0048] 如图IBB所示,从这两个微带反射数组天线(现有的微带反射数组天线与本发明第一较佳实施例的微带反射数组天线)反射而出的高频信号的具有Y极化方向的部分在各个角度值(Θ)下的强度分布(即散射场)大致相同,且代表两个微带反射数组天线的两条曲线(分别以”◊”及”-“表示)并无显著差异。 [0048] As shown in FIG IBB, two high-frequency signal from the microstrip antenna reflector arrays (micro-strip reflect array antennas of the first preferred embodiment of the conventional micro-strip reflect array antenna of the present invention) out of the reflected moiety Y having the respective polarization directions in the angular distribution of the intensity ([Theta]) (i.e., fringe field) is substantially the same, and the two curves representative of two micro-strip reflect array antenna (respectively "◊" and "-" representation) was not significantly different. 由于号角天线发射至这两个微带反射数组天线的反射板的信号为具Y方向极化的高频信号,所以此一现象显示出这两个微带反射数组天线不论在任何角度值(Θ)下,两者的共极化位准(co-polarization level)大致相同。 Since the horn antenna to transmit a signal reflecting plate reflecting the two microstrip antenna arrays for a high frequency signal having the polarization direction Y, so that this phenomenon shows the two micro-strip reflect array antenna regardless of the value at any angle ([Theta] under), both co-polarization level (co-polarization level) is substantially the same.

[0049] 但是,需注意的是,如图IBB下半部分所示,从这两个微带反射数组天线(现有的微带反射数组天线与本发明第一较佳实施例的微带反射数组天线)反射出的高频信号的具有X极化方向的部分在各个角度值(Θ)下的强度分布(即散射场)却存在者显著差异, 两条曲线不仅相差甚多,且本发明第一较佳实施例的微带反射数组天线的曲线(以”〇”表示)显著低于现有微带反射数组天线的曲线(以” * ”表示)。 [0049] However, it should be noted that, as shown in the lower half of FIG IBB divided, from two microstrip array antenna reflector (reflector conventional microstrip antenna array of the first preferred embodiment of the present invention reflection microstrip X portion having a direction of polarization of the antenna array) reflected high-frequency signal in a respective angular value of the intensity distribution (i.e., fringe field) ([Theta]) in the presence, but were significantly different, the two curves differ only very much, and the present invention microstrip antenna array reflection curve of the first preferred embodiment (indicated by "square") is significantly lower than the conventional micro-strip reflect array antenna curve (indicated by "*" indicates). 此外,由于号角天线发射至这两个微带反射数组天线的反射板的信号为具Y方向极化的高频信号,所以本发明第一较佳实施例的微带反射数组天线的交叉极化位准不论在任何角度值(Θ)下均显著低于现有微带反射数组天线的交叉极化位准。 Further, since the high-frequency signal to the signal transmitting horn antenna reflector plate reflecting the two microstrip array antenna is polarized with the Y-direction, the reflected cross-polarized microstrip antenna array of the first preferred embodiment of the present invention any level regardless of the value of the angle ([Theta]) were significantly lower than the conventional micro-strip reflect array antenna cross-polarization level.

[0050] 图4是显示实际量测此两种天线(现有微带反射数组天线与本发明第一较佳实施例的微带反射数组天线)在9GHz至12GHz的频率范围内在瞄准在线辐射增益值,亦即比较两者在瞄准在线共极化增益(bore sightco-polarization gain)与交叉极化增益(cross-polarization gain)的结果,其中,在此频率范围内(9GHz至12GHz),由于代表这两个微带反射数组天线(现有的微带反射数组天线与本发明第一较佳实施例的微带反射数组天线)的瞄准在线共极化增益的两条曲线(分别以”▽”及”-“表示)在整个频率范围内(9GHz至12GHz)并无显著差异,所以这两个微带反射数组天线瞄准在线共极化增益在整个频率范围内(9GHz至12GHz)内大致相同。 [0050] FIG. 4 is a graph showing actual measurement these two antennas (conventional micro-strip reflect array antenna and a first preferred embodiment the microstrip antenna reflector array embodiment of the present invention) aimed at inner line radiation gain in the frequency range of 12GHz to 9GHz value, i.e., the comparison result of the aiming line in both co-polarized gain (bore sightco-polarization gain) and the gain cross-polarization (cross-polarization gain), wherein, in this frequency range (9GHz to 12GHz), since representatives the two microstrip array antenna reflector (reflective array of conventional microstrip antenna of the present invention, a first reflective array antenna microstrip preferred embodiment) aiming line co-polarized two gain curves (respectively "▽" and "-") of no significant difference in the entire frequency range (9GHz to 12GHz), so that two reflective arrays microstrip line co-polarized antenna boresight gain substantially equal to the inner (9GHz to 12GHz) in the entire frequency range.

[0051] 但是,如图4下半部分所示,代表这两个微带反射数组天线(现有的微带反射数组天线与本发明第一较佳实施例的微带反射数组天线)的交叉极化增益的两条曲线在在整个频率范围内(9GHz至12GHz)内则存在者显著差异,两条曲线相差甚大,本发明第一较佳实施例的微带反射数组天线的曲线(以”〇”表示)显著低于现有微带反射数组天线的曲线(以” 表示)。因此,在整个频率范围内(9GHz至12GHz)内,本发明第一较佳实施例的微带反射数组天线的交叉极化增益均显著低于现有微带反射数组天线的交叉极化增益。 [0051] However, as shown in the lower half 4 minutes, representatives of the two micro-strip reflect array antenna (microstrip antenna reflector array reflecting the conventional microstrip antenna array in the first preferred embodiment of the present invention) cross polarization gain in the presence of the two curves (9GHz to 12GHz) in the entire frequency range are significantly different, a difference of the two curves is very large, the curve of the micro-strip reflect array antenna of a first preferred embodiment of the present invention (in " square ") are significantly lower than the conventional curve microstrip array antenna reflector (dimension" representation). Thus, the entire frequency range (9GHz to 12GHz), a first micro-strip reflect array antenna of the preferred embodiment of the present invention the cross-polarization gain were significantly lower than the conventional micro-strip reflect array antenna cross-polarization gain.

[0052] 图5是实际量测此两种天线(现有微带反射数组天线与本发明第一较佳实施例的微带反射数组天线)在10.4GHz的频率下,两者在磁场平面(H-plane)上所具有的共极化辐射图样(co-polarization radiationpattern)与交叉极化辐射图样(cross-polarization radiationpattern)。 [0052] FIG. 5 is an actual measurement these two antennas (conventional micro-strip reflect array antenna and a first preferred embodiment the microstrip antenna reflector array embodiment of the present invention) at a frequency of 10.4GHz, both the magnetic field plane ( the H-plane) with the co-polarized radiation pattern (co-polarization radiationpattern) and cross-polarization radiation pattern (cross-polarization radiationpattern). 如图5所示,在此一频率下(10. 4GHz),由于代表这两个微带反射数组天线(现有的微带反射数组天线与本发明第一较佳实施例的微带反射数组天线)的位于磁场平面的共极化辐射图样的两条曲线(分别以”_”及”一”表示) 在各个角度值(θ )下并无显著差异。 As shown, at this frequency (10. 4GHz), since the representatives of the two micro-strip reflect array antenna of the first preferred embodiment of the micro-strip reflect array (conventional micro-strip reflect array antenna of the present invention 5 antenna) magnetic fields at the plane co-polar radiation pattern of the two curves (each indicated by "_" and "a") were not significantly different at each angle value (θ). 所以,这两个微带反射数组天线的不论在任何角度值(θ )下,位于磁场平面的共极化辐射图样大致相同。 Therefore, regardless of the value at any angle ([theta]), is located in the plane of the magnetic field is substantially the same co-polar radiation pattern of the two micro-strip reflect array antenna.

[0053] 但是,如图5下半部分所示,代表这两个微带反射数组天线(现有的微带反射数组天线与本发明第一较佳实施例的微带反射数组天线)的位于磁场平面的交叉极化辐射图样在各个角度值(Θ)下则存在差异,且本发明第一较佳实施例的微带反射数组天线的曲线(以” •”表示)低于现有微带反射数组天线的曲线(以”〇”表示)。 [0053] However, as shown in the lower half 5 minutes, representatives of the two micro-strip reflect array antenna (conventional micro-strip reflect array antenna and a first preferred embodiment the microstrip antenna reflector array embodiment of the present invention) is positioned cross-polarized radiation pattern in the plane of the magnetic field differ at each angle value (Θ), and the micro-strip reflect array antenna of a first preferred embodiment of the present invention, curve (indicated by "•") lower than the conventional microstrip curve reflecting array antenna (indicated by "square"). 因此,在此一频率(10. 4GHz),本发明第一较佳实施例的微带反射数组天线的位于磁场平面交叉极化辐射图样不论在任何角度值(Θ)下均显著低于现有微带反射数组天线的位于磁场平面交叉极化辐射图样。 Thus, the magnetic field located in the plane of a cross-polarized radiation pattern in this frequency (10. 4GHz), micro-strip reflect array antenna of a first preferred embodiment of the present invention is significantly lower than the prior regardless of any angle value ([Theta]) microstrip array antennas located in the magnetic field reflected cross-polarized radiation pattern plane.

[0054] 另一方面,除了使位于微带反射数组天线的反射板上表面的每一个微带天线单元所具的内环的第二直径为同一微带天线单元所具的外环的第一直径的比值的0.6倍外,两者之间的比值(第二直径的长度除以第一直径的长度)亦可为0. 4至0. 8之间的任何数值。 [0054] On the other hand, in addition to the first inner diameter of the second microstrip antenna that each unit is located on the reflector surface of the micro-strip reflect array antenna having the microstrip antenna element is the same as the outer ring having 0.6 times the outer diameter ratio, the ratio between the two (length of the second length divided by the diameter of the first diameter) may be any value between 0.4 to 0.8. 但是,当此一比值改变的时候,此微带反射数组天线的交叉极化位准也会随的改变。 However, when this ratio is changed, this cross-polarized micro-strip reflect array bit antenna with quasi also change. 以本发明第一较佳实施例的微带反射数组天线为例,其每一个微带天线单元的第二直径/第一直径比值为0. 6,而其交叉极化位准则约为36dB。 Microstrip antenna array reflecting a first preferred embodiment of the present invention, an example embodiment, each of a diameter of the second microstrip antenna element / first diameter ratio of 0.6, while the cross-polarization bits guidelines about 36dB. 但是,若将每一微带反射数组天线的反射板所具的每一微带天线单元的第二直径/第一直径比值改变为0. 8,则此一微带反射数组天线的交叉极化位准便会衰退为20dB,即此一微带反射数组天线所接收到的噪声(一具有另一极化方向的信号)较大。 However, when each of the second diameter of each microstrip antenna element microstrip array antenna reflector having a reflector plate / first diameter ratio was changed to 0.8, this microstrip antenna array cross-polarized reflected level will decline as 20dB, i.e., noise (a signal having another polarization direction) of a micro-strip reflect array this large antenna received.

[0055] 图6是位于本发明第二较佳实施例的微带反射数组天线的反射板上表面的微带天线单元的示意图。 [0055] FIG. 6 is a schematic view of a microstrip antenna element on the reflector surface of the micro-strip reflect array antenna in a second preferred embodiment of the present invention. 在本发明第二较佳实施例的微带反射数组天线中,位于微带反射数组天线的反射板上表面的每一个微带天线单元61均具有一正方形的内环62与一正方形的外环63,且内环62的几何中心点(图中未示)与外环63的几何中心点(图中未示)重合。 Microstrip antenna array reflecting a second preferred embodiment of the present invention, the reflective surface of the micro-strip reflect array panel antenna of each microstrip antenna element 61 has a square inner ring 62 and a square outer ring 63, the inner ring 62 and the geometric center (not shown) and the geometric center of the outer ring (not shown) 63 coincide. 此外,外环63与内环62分别挖设有两个第一沟槽64及两个第二沟槽65,使外环63与内环62均分隔成两段。 Further, the outer ring 63 and inner ring 62 are provided with two digging first trenches 64 and the two second grooves 65, 63 so that the outer ring and the inner ring 62 is divided into two sections. 最后,位于本发明第二较佳实施例的微带反射数组天线的反射板上表面的每一个微带天线单元的外环63的边长是依据其位于反射板上表面的位置而定。 Finally, the outer side length of each microstrip antenna element on the reflector surface of the micro-strip reflect array antenna in a second preferred embodiment of the present invention 63 is based on a position which is located on the reflector surface may be.

[0056] 图7是位于本发明第三较佳实施例的微带反射数组天线的反射板上表面的微带天线单元的示意图。 [0056] FIG. 7 is a schematic diagram of a microstrip antenna element on the reflector surface of the micro-strip reflect array antenna in the third preferred embodiment of the present invention. 在本发明第三较佳实施例的微带反射数组天线中,位于微带反射数组天线的反射板上表面的每一个微带天线单元71均具有一六角形的内环72与一六角形的外环73,且内环72的几何中心点(图中未示)与外环73的几何中心点(图中未示)重合。 Microstrip antenna array reflecting a third preferred embodiment of the present invention, the reflecting plate surface of each microstrip antenna element is positioned microstrip array antenna reflector 71 has a hexagonal inner ring 72 with a hexagonal the outer ring 73 and inner ring 72 of the geometric center (not shown) coincides with the geometric center of the outer ring (not shown) 73. 此外,外环73与内环72分别挖设有两个第一沟槽74及两个第二沟槽75,使外环73与内环72均分隔成两段。 Further, the outer ring 73 and inner ring 72 are provided with two digging first trenches 74 and the two second grooves 75, 73 so that the outer ring and the inner ring 72 are separated into two sections. 最后,位于本发明第三较佳实施例的微带反射数组天线的反射板上表面的每一个微带天线单元的外环7微带反射数组天线的3的边长是依据其位于反射板上表面的位置而定。 Finally, the side length of the outer ring 7 micro-strip reflect array antennas each microstrip antenna element on the reflector surface of the micro-strip reflect array antenna in the third preferred embodiment 3 of the present invention is based on the reflection plate positioned depending on the position of the surface.

[0057] 因此,通过由在本发明的微带反射数组天线的每一微带天线单元的外环及内环挖设两个第一沟槽及两个第二沟槽(即两个第一沟槽的联机方向平行于两个第二沟槽的联机方向),当本发明的微带反射数组天线处于其「接收状态」时,本发明的微带反射数组天线可利用这些沟槽有效地隔绝其微带天线单元因一极化方向垂直于两个第一沟槽的联机方向的高频信号而产生的感应电流,使得本发明的微带反射数组天线仅能接收一极化方向平行于两个第一沟槽的联机方向的高频信号,大幅减低本发明的微带反射数组天线接收到一极化方向垂直于两个第一沟槽的联机方向的高频信号的机会,有效地降低其交叉极化位准。 [0057] Thus, by the outer ring and the inner ring of each microstrip antenna element microstrip antenna array according to the present invention, the reflection of the two first trenches dug trench and a second two (i.e. first two line parallel to the direction of the grooves of the second groove line direction of the two), when the micro-strip reflect array antenna of the present invention in which the "reception status" micro-strip reflect array antenna of the present invention can utilize effectively the grooves microstrip antenna element which is isolated due to a polarization direction perpendicular to the line direction of the two high-frequency signals of the first trench and the induced current, so that the micro-strip reflect array antenna of the present invention can receive only a polarization direction parallel to the two high-frequency signal line direction of the first trenches, the present invention substantially reduce microstrip array antenna receives a reflected direction of polarization perpendicular to the high frequency signal opportunity line direction of the two first trenches effectively reducing the cross-polarization level. 所以,通过由使用本发明的微带反射数组天线,卫星通讯系统便可以利用同一个频率同时传送两种或两种以上的信号(每一种信号均具有不同的极化方向),大幅提升卫星通讯系统的容量及信号的接收品质。 Therefore, two or more transmission signals reflected by the microstrip array antenna of the present invention, the satellite communication system can use the same frequency simultaneously (each signal having a different polarization directions), dramatically satellite the reception quality and capacity of communication system signals.
