具有高隔離度的天線裝置 Antenna device with high isolation

本發明係關於一種天線裝置，尤指一種可反射發射天線發出之輻射波的天線裝置。 The present invention relates to an antenna device, and more particularly to an antenna device that can reflect radiation waves emitted by a transmitting antenna.

先前技術之天線裝置中係具有發射天線(transmitter antenna)與接收天線(receiver antenna)。發射天線用以發射輻射波(依應用不同可為HF、VHF或UHF等不同頻率之輻射波)至天線裝置之外部，接收天線則用以接收來自天線裝置外部的輻射波。典型兼具發射天線與接收天線之天線裝置，可例如為雷達裝置，其須先以發射天線發射輻射波後，再以接收天線接收外部物體反射之輻射波以供後續分析。為保護發射天線、接收天線與相關設備，實務上必須以天線罩(radome)容置發射天線與接收天線，以避免其暴露於陽光或濕氣而毀損。然而，如第1圖之先前技術的天線裝置100示意圖所示，發射天線ANT1發射之輻射波Ra接觸到天線罩110內壁所產生的反射波Ra’，係天線裝置不欲接收之輻射波，卻會由接收天線ANT2接收，而有礙於接收天線ANT2正確接收來自天線裝置100外部的輻射波Rb。因此，本領域實需一解決方案以消除天線罩110內壁所產生的反射波Ra’於接收天線ANT2處產生的效應。 A prior art antenna device has a transmitter antenna and a receiver antenna. The transmitting antenna is used to emit radiation waves (which may be radiated waves of different frequencies such as HF, VHF or UHF depending on the application) to the outside of the antenna device, and the receiving antenna is used to receive the radiated waves from the outside of the antenna device. A typical antenna device having both a transmitting antenna and a receiving antenna may be, for example, a radar device that first transmits a radiation wave with a transmitting antenna and then receives a radiation wave reflected by an external object with a receiving antenna for subsequent analysis. In order to protect the transmitting antenna, the receiving antenna and related equipment, it is practical to accommodate the transmitting antenna and the receiving antenna with a radome to prevent it from being damaged by exposure to sunlight or moisture. However, as shown in the schematic diagram of the antenna device 100 of the prior art of FIG. 1, the reflected wave Ra' generated by the radiation wave Ra emitted by the transmitting antenna ANT1 contacting the inner wall of the radome 110 is a radiation wave that the antenna device does not want to receive. However, it is received by the receiving antenna ANT2, and the receiving antenna ANT2 is prevented from correctly receiving the radiated wave Rb from the outside of the antenna device 100. Therefore, there is a need in the art for a solution to eliminate the effect of the reflected wave Ra' generated at the inner wall of the radome 110 at the receiving antenna ANT2.

The antenna device 200 includes a transmitting antenna ANT _Tx , a receiving antenna ANT _Rx , a reflector 210 and a radome 220. The transmitting antenna ANT _{Tx is} used to emit a radiation wave R0 having a polarization direction of the direction D1 toward the front of the transmitting antenna ANT _Tx . The receiving antenna ANT _{Rx is} used to receive radiation waves. The reflector 210 is disposed before the transmitting antenna ANT _Tx and the receiving antenna ANT _Rx to reflect a small portion of the radiated wave R0 emitted by the transmitting antenna ANT _Tx to generate the reflected radiated wave R01; the radiating wave emitted by the transmitting antenna ANT _Tx Most of R0 can be transmitted through the reflector 210 to produce a transmitted radiation wave R1. The radome 220 is configured to provide an accommodating space for accommodating the transmitting antenna ANT _Tx , the receiving antenna ANT _{Rx ,} and the reflecting member 210 . At the same time, the radome 220 also reflects a small portion of the radiation wave R1 to generate a reflected radiation wave R11, and most of the radiation wave R1 can be transmitted through the radome 220 to generate a transmitted radiation wave R2.

第3圖係本發明實施例之反射件210的示意圖。反射件210包含框架2101。框架2101包含兩橫桿21011，實質上平行於輻射波R0之極化方向(方向D1)，及兩縱桿21012，實質上垂直於方向D1。反射件210亦包含至少一反射柵桿2102，每一反射柵桿2102連接於兩橫桿21011，且實質上垂直於方向D1。 Figure 3 is a schematic illustration of a reflector 210 in accordance with an embodiment of the present invention. The reflector 210 includes a frame 2101. The frame 2101 includes two crossbars 21011 that are substantially parallel to the polarization direction of the radiated wave R0 (direction D1) and the two longitudinal bars 21012, substantially perpendicular to the direction D1. The reflector 210 also includes at least one reflective grid 2102, each reflective grid 2102 being coupled to the two rails 21011 and substantially perpendicular to the direction D1.

第4圖係本發明實施例之天線裝置200的局部示意圖。天線裝置200包含背板230，發射天線ANT_Tx及接收天線ANT_Rx係固定於背板230上，背板230上具有滑軌240，滑軌240的軌道方向係實質上平行於發射天線ANT_Tx發射之電磁波R0的極化方向，亦即實質上平行於方向D1。天線裝置200另包含連接件250，其第一端係固定於反射件210，第二端係以可沿滑軌240滑動的方式設置於滑軌240上。因此，反射件210可藉由連接件250與滑軌240沿方向D1滑動。上述的連接件250可更包含可調整長度之伸縮單元(例如以實軸與空心套軸所組成之伸縮單元；或由具有多個排狀穿孔之第一子連接件與具有多個排狀螺絲孔之第二子連接件組成之可允許長度調整後再以螺絲鎖固之長度可調整的伸縮單元)，用以伸縮調整連接件250之長度以調整反射件210與發射天線ANT_Tx/接收天線ANT_Rx之間的距離，藉此可調整第2圖所示之輻射波R01的相位以改善天線之間的隔離度而使接收天線ANT_Rx之接收效果更佳。 Figure 4 is a partial schematic view of an antenna device 200 in accordance with an embodiment of the present invention. The antenna device 200 includes a backplane 230. The transmitting antenna ANT _Tx and the receiving antenna ANT _Rx are fixed on the backplane 230. The backplane 230 has a sliding rail 240. The orbital direction of the sliding rail 240 is substantially parallel to the transmitting antenna ANT _Tx. The polarization direction of the electromagnetic wave R0, that is, substantially parallel to the direction D1. The antenna device 200 further includes a connecting member 250, the first end of which is fixed to the reflecting member 210, and the second end is disposed on the sliding rail 240 so as to be slidable along the sliding rail 240. Therefore, the reflecting member 210 can slide in the direction D1 by the connecting member 250 and the slide rail 240. The connecting member 250 may further comprise an adjustable length telescopic unit (for example, a telescopic unit composed of a solid shaft and a hollow sleeve shaft; or a first sub-connector having a plurality of rows of perforations and a plurality of row screws) The second sub-connector of the hole is composed of a telescopic unit which can be adjusted in length after being adjusted by a screw, and is used for telescopically adjusting the length of the connecting member 250 to adjust the reflecting member 210 and the transmitting antenna ANT _Tx / receiving antenna The distance between the ANT _Rx , by which the phase of the radiation wave R01 shown in Fig. 2 can be adjusted to improve the isolation between the antennas and to better the reception effect of the receiving antenna ANT _Rx .

第2至4圖所示之天線裝置200中，使用者可將反射件210於滑軌240上沿方向D1移動調整，以使發射天線ANT_Tx發出之輻射波R0經反射件210反射產生之輻射波R01，相較於輻射波R1經天線罩220反射產生之輻射波R11，於接收天線ANT_Rx處朝向振幅相同且相位相反的理想狀態調整，而盡量使輻射波R01與輻射波R11得以互相抵銷。如第2圖所示，接收天線ANT_Rx接收來自天線裝置200外部之輻射波R3時，將較不受輻射波R11干擾。 In the antenna device 200 shown in FIGS. 2 to 4, the user can move the reflector 210 on the slide rail 240 in the direction D1 so that the radiation wave R0 emitted from the transmitting antenna ANT _Tx is reflected by the reflector 210. The wave R01 is compared with the radiation wave R11 generated by the radiation wave R1 reflected by the radome 220, and is adjusted toward the ideal state of the same amplitude and opposite phase at the receiving antenna ANT _Rx , and the radiation wave R01 and the radiation wave R11 are mutually offset as much as possible. pin. As shown in Fig. 2, when the receiving antenna ANT _Rx receives the radiated wave R3 from the outside of the antenna device 200, it is less likely to interfere with the radiated wave R11.

如第4圖所示，發射天線ANT_Tx與接收天線ANT_Rx具有若干天線刻槽(slot)S1，於第3圖所示的實施例中，多個天線刻槽S1係垂直於方向D1且加上各自之傾斜角度，刻製於發射天線ANT_Tx與接收天線ANT_Rx，以使發射天線ANT_Tx發射之輻射波R1具有方向D1之極化方向，並使接收天線ANT_Rx可用以接收極化方向平行於方向D1之輻射波。第2至3圖揭露之反射件210，因其反射柵桿2102係垂直於第2圖所示之輻射波R0的極化方向(方向D1)，故第2圖所示的輻射波R0可大部分穿透反射件210，因此反射件210之面積可允許為涵蓋發射天線ANT_Tx之開口範圍而不至於影響發射天線ANT_Tx之發射效率與輻射場形。上述之橫桿21011與縱桿21012可係為(但不限於)矩形，以使橫桿21011與縱桿21012形成之間隙係為(但不限於)長條形之矩形間隙，例如為長邊平行於方向D2且短邊平行於方向D1的長條形之矩形間隙，其中方向D2係垂直於方向D1之方向。上述發射天線ANT_Tx與接收天線ANT_Rx之多個天線刻槽S1中，每一天線刻槽S1之傾斜角度係各自對應於天線刻槽S1之位置所發射或接收之輻射波的振幅強度。於本發明實施例中，其發射之輻射波R0的極化方向係對應於垂直於發射天線ANT_Tx之天線刻槽S1的方向而為方向D1。此外，根據第4圖之實施例，因接收天線ANT_Rx之天線刻槽S1亦實質上垂直於方向D1，故接收天線ANT_Rx所接收之輻射波(如第2圖所示的輻射波R3)的極化方向亦設定為方向D1。 As shown in FIG. 4, the transmitting antenna ANT _Tx and the receiving antenna ANT _Rx have a plurality of antenna slots S1. In the embodiment shown in FIG. 3, the plurality of antenna slots S1 are perpendicular to the direction D1 and are added. The respective tilt angles are engraved on the transmitting antenna ANT _Tx and the receiving antenna ANT _Rx such that the radiating wave R1 emitted by the transmitting antenna ANT _Tx has a polarization direction of the direction D1, and the receiving antenna ANT _Rx can be used to receive the polarization direction. Radiation waves parallel to direction D1. In the reflection member 210 disclosed in FIGS. 2 to 3, since the reflection grating rod 2102 is perpendicular to the polarization direction (direction D1) of the radiation wave R0 shown in FIG. 2, the radiation wave R0 shown in FIG. 2 can be large. partial penetration reflective member 210, and therefore the area of the reflecting member 210 may be allowed to cover the opening range of the transmitting antenna _Tx ANT and does not affect the efficiency of transmit antenna _Tx ANT shape of the radiation field. The crossbar 21011 and the vertical rod 21012 may be, but not limited to, rectangular, such that the gap formed by the crossbar 21011 and the longitudinal rod 21012 is, but not limited to, an elongated rectangular gap, for example, a long side parallel An elongated rectangular gap in the direction D2 and having a short side parallel to the direction D1, wherein the direction D2 is perpendicular to the direction of the direction D1. In the plurality of antenna slots S1 of the transmitting antenna ANT _Tx and the receiving antenna ANT _Rx , the tilt angle of each antenna slot S1 is an amplitude intensity of a radiation wave transmitted or received corresponding to the position of the antenna slot S1. In the embodiment of the present invention, the polarization direction of the emitted radiation wave R0 corresponds to the direction perpendicular to the antenna slot S1 of the transmitting antenna ANT _Tx and is the direction D1. Further, according to the embodiment of FIG. 4, since the antenna notch S1 of the receiving antenna ANT _Rx is also substantially perpendicular to the direction D1, the receiving radiation wave received by the antenna ANT _Rx (such as the radiated wave R3 shown in FIG. 2) The polarization direction is also set to direction D1.

第5圖係天線裝置200之另一視角的示意圖，其中天線罩220係以透明示意，可見發射天線ANT_Tx、接收天線ANT_Rx及反射件210被容置於天線罩220內部之佈局，固定單元290係用以安裝固定天線罩220。 5 is a schematic view of another view of the antenna device 200, wherein the radome 220 is transparent, and the visible antenna ANT _Tx , the receiving antenna ANT _Rx and the reflective member 210 are housed in the radome 220, and the fixing unit is shown. The 290 is used to mount the fixed radome 220.

第6至8圖係本發明另一實施例之天線裝置500的局部示意圖。天線裝置500相較於天線裝置200，係具有兩個反射件，因此天線裝置500具有第一反射件5101與第二反射件5102，其中第一反射件5101與第二反射件5102包含之框架、縱桿及橫桿因類似於第3圖所示之反射件210，故不再贅述。天線裝置500中，用以固定發射天線ANT_Tx與接收天線ANT_Rx之背板530上可於發射天線ANT_Tx與接收天線ANT_Rx之間設置第一滑軌5401與第二滑軌5402。第一連接件5201之第一端固定於第一反射件5101，第二端以可沿第一滑軌5401滑動的方式設置於第一滑軌5401上。第二連接件5202之第一端固定於第二反射件5102，第二端以可沿第二滑軌5402滑動的方式設置於第二滑軌5402上。藉此，第一反射件5101與第二反射件5102可各自沿方向D1滑動調整。於此實施例中，第一連接件5201之長度可例如大於第二連接件5202之長度(如第6圖所示)，以使第一反射件5101相較於第二反射件5102距離背板530更遠。因此，第一反射件5101與第二反射件5102於滑動調整時，其位置可完全重疊、部分重疊或完全不重疊(如第7至8圖所示)。參照第2圖與第6至8圖，藉由第一反射件5101與第二反射件5102之重疊程度，可調整輻射波R01之反射量，而助於使用者調整得到最適之輻射波R01以減低輻射波R11造成的干擾。 6 to 8 are partial schematic views of an antenna device 500 according to another embodiment of the present invention. The antenna device 500 has two reflecting members compared to the antenna device 200. Therefore, the antenna device 500 has a first reflecting member 5101 and a second reflecting member 5102, wherein the first reflecting member 5101 and the second reflecting member 5102 comprise a frame, Since the vertical rod and the cross rod are similar to the reflecting member 210 shown in Fig. 3, they will not be described again. The antenna device 500, to fix the transmitting antenna may be disposed on a first transmit antenna and the second slide rail 5401 between 5402 and receive antenna ANT _Tx ANT _Rx and on the back plate 530 ANT _Tx ANT _Rx of the receiving antenna. The first end of the first connecting member 5201 is fixed to the first reflecting member 5101, and the second end is disposed on the first sliding rail 5401 so as to be slidable along the first sliding rail 5401. The first end of the second connecting member 5202 is fixed to the second reflecting member 5102, and the second end is disposed on the second sliding rail 5402 so as to be slidable along the second sliding rail 5402. Thereby, the first reflecting member 5101 and the second reflecting member 5102 can each be slidably adjusted in the direction D1. In this embodiment, the length of the first connecting member 5201 can be, for example, greater than the length of the second connecting member 5202 (as shown in FIG. 6), so that the first reflecting member 5101 is spaced from the backing plate by the second reflecting member 5102. 530 farther. Therefore, when the first reflecting member 5101 and the second reflecting member 5102 are adjusted in sliding, their positions may completely overlap, partially overlap, or not overlap at all (as shown in FIGS. 7 to 8). Referring to FIG. 2 and FIG. 6 to FIG. 8 , the amount of reflection of the radiation wave R01 can be adjusted by the degree of overlap between the first reflection member 5101 and the second reflection member 5102, and the user can adjust the optimum radiation wave R01.

第6至8圖之示例係第一反射件5101與第二反射件5102可分別滑動調整之實施例，然而根據本發明另一實施例，亦可將長度較長之第一連接件5201與長度較短之第二連接件5202皆以可沿滑軌滑動的方式設置於同一滑軌上，以使第一連接件5201與第二連接件5202分別連接之第一反射件5101與第二反射件5102可分別滑動調整以致完全重疊、部分重疊或完全不重疊。又如第9圖之本發明實施例的天線裝置600之局部示意圖所示，可在背板630上，將第一滑軌6401安裝於接收天線ANT_Rx上方(例如將第一滑軌6401安裝於背板630上，或將第一滑軌6401安裝於接收天線ANT_Rx之天線隔板RB_Rx，其中接收天線ANT_Rx之天線隔板RB_Rx係如第6圖之天線隔板RB_Rx所示)，並將第一反射件6101之框架上側的橫桿嵌入第一滑軌6401以使第一反射件6101可滑動調整；及將第二滑軌6402安裝於發射天線ANT_Tx下方(例如將第二滑軌6402安裝於背版630上，或將第二滑軌6402安裝於發射天線ANT_Tx之天線隔板RB_Tx，其中發射天線ANT_Tx之天線隔板RB_Tx係如第6圖之天線隔板RB_Tx所示)，並將第二反射件6102之框架下側的橫桿嵌入第二滑軌6402以使第二反射件6102可滑動調整，以滑動調整第一反射件6101與第二反射件6102使其完全重疊、部分重疊或完全不重疊。第9圖之實施例係以第一反射件與第二反射件各安裝於一滑軌為例，使用者亦可於每一反射件上下各安裝一滑軌並將反射件上下側之橫桿皆嵌入滑軌以供滑動調整，然需將滑軌前後錯開，以使多個反射件得以重疊。根據本發明實施例，如第6至9圖所示之第一反射件與第二反射件之間的前後距離可經研發人員藉由軟體模擬與實驗量測求得最適之距離。 The examples of FIGS. 6 to 8 are embodiments in which the first reflecting member 5101 and the second reflecting member 5102 can be respectively slidably adjusted. However, according to another embodiment of the present invention, the first connecting member 5201 having a longer length can also be used. The second second connecting member 5202 is disposed on the same sliding rail so as to be slidable along the sliding rail, so that the first connecting member 5201 and the second connecting member 5202 are respectively connected to the first reflecting member 5101 and the second reflecting member. The 5102 can be individually slidably adjusted so as to be completely overlapping, partially overlapping, or not overlapping at all. As shown in the partial schematic diagram of the antenna device 600 of the embodiment of the present invention, the first sliding rail 6401 can be mounted on the backplane 630 above the receiving antenna ANT _Rx (for example, the first sliding rail 6401 is mounted on the back rail 630). the backplane 630, or 6401 first rail attached to the receiving antenna ANT _Rx separator RB _Rx antenna, wherein the antenna ANT _Rx of the receiving antenna based separator RB _Rx antenna of FIG. 6 as the first separator shown RB _Rx) And inserting the crossbar on the upper side of the frame of the first reflecting member 6101 into the first sliding rail 6401 to make the first reflecting member 6101 slidably adjustable; and mounting the second sliding rail 6402 under the transmitting antenna ANT _Tx (for example, the second rail 6402 mounted on a back plate 630, or the second slide rail 6402 is attached to the transmitting antenna ANT _Tx separator RB _Tx antennas, wherein the transmit antenna ANT _Tx antennas based separator RB _Tx antenna as in FIG. 6 of the separator The RB _{Tx is} shown), and the crossbar on the lower side of the frame of the second reflecting member 6102 is embedded in the second sliding rail 6402 to slidably adjust the second reflecting member 6102 to slidably adjust the first reflecting member 6101 and the second reflecting member. The 6102 is made to overlap completely, partially overlap, or not overlap at all. In the embodiment of FIG. 9 , the first reflecting member and the second reflecting member are respectively mounted on a sliding rail. The user can also install a sliding rail on each of the upper and lower reflecting members and the upper and lower sides of the reflecting member. The slide rails are all embedded for sliding adjustment, but the slide rails are staggered back and forth so that the plurality of reflectors are overlapped. According to the embodiment of the present invention, the front-rear distance between the first reflecting member and the second reflecting member as shown in FIGS. 6 to 9 can be optimized by the developer through software simulation and experimental measurement.

上述用以反射第2圖所示之輻射波R0之反射件210、第一反射件5101、第二反射件5102、第一反射件6101及第二反射件6102，係由框架與垂直於輻射波R0之極化方向(方向D1)之至少一反射柵桿所組成。根據本發明實施例，上述之反射件亦可僅由一組垂直於輻射波R0之極化方向(方向 D1)之複數個反射柵桿所組成。第10至11圖係本發明另一實施例中，用以反射如第2圖所示之輻射波R0以產生輻射波R01之反射柵桿組710之示意圖。每一反射柵桿組710包含複數個反射柵桿7102，因其方向係垂直於輻射波R0之極化方向(方向D1)，故發射天線ANT_Tx發出之輻射波R0其大部分可穿越反射柵桿組710，僅少部份反射產生輻射波R01，而不致過度影響輻射波R0之發射效率。類似於第4圖、第6至8圖與第9圖之實施例所述，如第11圖所示，反射柵桿組710亦可藉由連接件720及滑軌等零件，連接於天線裝置之背板或天線隔板，以沿方向D1滑動調整。 The reflector 210 for reflecting the radiation wave R0 shown in FIG. 2, the first reflector 5101, the second reflector 5102, the first reflector 6101 and the second reflector 6102 are framed and perpendicular to the radiation wave. The polarization direction of R0 (direction D1) is composed of at least one reflection grid. According to an embodiment of the invention, the reflective member may also be composed of only a plurality of reflective grating bars perpendicular to the polarization direction (direction D1) of the radiation wave R0. 10 to 11 are schematic views of a reflection grid group 710 for reflecting the radiation wave R0 as shown in Fig. 2 to generate a radiation wave R01 in another embodiment of the present invention. Each of the reflection grid sets 710 includes a plurality of reflection grids 7102. Since the direction is perpendicular to the polarization direction of the radiation wave R0 (direction D1), most of the radiation waves R0 emitted by the transmission antenna ANT _Tx can pass through the reflection grid. In the rod group 710, only a small portion of the reflection generates the radiation wave R01 without excessively affecting the emission efficiency of the radiation wave R0. Similar to the embodiment of FIG. 4, FIG. 6 to FIG. 8 and FIG. 9, as shown in FIG. 11, the reflection grid set 710 can also be connected to the antenna device by means of a connecting member 720 and a slide rail. The back plate or the antenna spacer is slidably adjusted in the direction D1.

第12至14圖係本發明實施例之反射柵桿組8101、反射柵桿組8102及反射柵桿組8103的示意圖。反射柵桿組8101、8102及8103同第10圖之反射柵桿組710，亦包含複數個反射柵桿7102，然而，為增強結構，根據本發明實施例亦可以至少一連桿連接多個反射柵桿。舉例而言，第12圖之反射柵桿組8101中，即以三連桿81011連接於三反射柵桿7102的兩兩之間。第13圖之反射柵桿組8102中，則以連桿81021連接四反射柵桿7102。而第14圖之反射柵桿組8103中，則以三連桿81031連接四反射柵桿7102。如第12至14圖實施例揭露的反射柵桿組8101、反射柵桿組8102及反射柵桿組8103中，其位於反射柵桿與連桿之間，用以供輻射波R1穿透之間隙(如第14圖之間隙819)，其垂直於輻射波R0之極化方向的長度應大於平行於輻射波R0之極化方向的長度，例如間隙819於平行於方向D2之長度應大於平行於方向D1之長度，方可使具有極化方向為方向D1之輻射波R0可大部份穿透如第12至14圖所示之反射柵桿組。以第13圖之反射柵桿組8102為例，亦可將一滑軌安裝於連桿81021，該滑軌係以可沿該極化方向滑動之方式設置於該連接件之第一端，並將連接件之第二端固定於天線裝置的背板上，或將連接件之第二端以可沿該極化方向滑動之方式設置於天線裝置之另一滑軌(其可設置於天線裝置之背板或天線隔板)上，以此達到可滑動調整反射柵桿組8102之功效。 12 to 14 are schematic views of a reflection grid group 8101, a reflection grid group 8102, and a reflection grid group 8103 according to an embodiment of the present invention. The reflective grid set 8101, 8102, and 8103 are the same as the reflective grid set 710 of FIG. 10, and also include a plurality of reflective grids 7102. However, in order to enhance the structure, at least one link may be connected to multiple reflections according to an embodiment of the present invention. Gate bar. For example, in the reflection grid group 8101 of FIG. 12, the three links 81011 are connected between the two of the three reflection grids 7102. In the reflection grid group 8102 of Fig. 13, the four reflection grids 7102 are connected by a link 81021. In the reflection grid group 8103 of Fig. 14, the four reflection grids 7102 are connected by a three-bar linkage 81031. In the reflective grid set 8101, the reflective grid set 8102 and the reflective grid set 8103 disclosed in the embodiments of FIGS. 12-14, it is located between the reflective grid and the connecting rod for the gap of the radiation wave R1. (As in the gap 819 of Fig. 14), the length perpendicular to the polarization direction of the radiation wave R0 should be greater than the length parallel to the polarization direction of the radiation wave R0, for example, the length of the gap 819 parallel to the direction D2 should be greater than parallel The length of the direction D1 is such that the radiation wave R0 having the polarization direction of the direction D1 can largely penetrate the reflection grid group as shown in FIGS. 12 to 14. For example, the reflection grid group 8102 of FIG. 13 may be mounted on the connecting rod 81021, and the sliding rail is disposed at the first end of the connecting member so as to be slidable along the polarization direction, and Fixing the second end of the connecting member to the back plate of the antenna device, or the second end of the connecting member is disposed on the other sliding rail of the antenna device in a manner slidable along the polarization direction (which can be disposed on the antenna device) a back plate or an antenna spacer) to achieve a slidable adjustment of the reflective grid The effect of the rod set 8102.

此外，如同第6至9圖實施例所示，天線裝置中亦可包含二組以上的反射柵桿組，藉由滑動調整以使多組反射柵桿組於發射天線ANT_Tx與接收天線ANT_Rx之前方彼此完全重疊、部分重疊或完全不重疊，以調整其反射之輻射波R01的振幅、相位及位置，以求得可將輻射波R11造成之干擾影響降至最低時所對應的反射柵桿組之位置。二組以上之反射柵桿組滑動調整時，其各自對應之連接件係可設置於同一滑軌或設置於多個滑軌上，以調整多組反射柵桿組之彼此重疊的程度。 In addition, as shown in the embodiments of FIGS. 6-9, the antenna device may also include two or more sets of reflective grids, and the plurality of sets of reflective grids are set by the sliding antenna to the transmitting antenna ANT _Tx and the receiving antenna ANT _Rx by sliding adjustment. The former sides completely overlap each other, partially overlap or not overlap at all, to adjust the amplitude, phase and position of the reflected radiation wave R01 to obtain a reflection grid rod corresponding to the interference effect caused by the radiation wave R11 is minimized. The location of the group. When two or more sets of reflective grids are slidably adjusted, the corresponding connecting members may be disposed on the same sliding rail or on a plurality of sliding rails to adjust the degree of overlapping of the plurality of reflective grating pole groups.

上述之滑軌，可為(但不限於)軌道形式之滑動式滑軌，或各自具有多段式排狀鎖孔之兩構件所構成之多段式滑軌，以利使用者滑動調整反射件或反射柵桿組且確定其位置後，藉由(但不限於)螺絲鎖固、焊接黏合、或卡榫接合等方式，將反射件或反射柵桿組固定於使用者所欲之位置。 The sliding rails mentioned above may be, but are not limited to, sliding sliding rails in the form of rails, or multi-segment slide rails composed of two members each having a multi-segment row-shaped locking hole, so as to facilitate sliding adjustment of the reflector or reflection by the user. After the grid is set and its position is determined, the reflector or the reflective grid is fixed to the user's desired position by, but not limited to, screwing, soldering, or snapping.

第15圖係本發明實施例中，發射天線ANT_Tx與接收天線ANT_Rx彼此左右錯位之示意圖。第15圖之實施例中，發射天線ANT_Tx與接收天線ANT_Rx可另以兩滑軌分別安裝於背板930上，以使發射天線ANT_Tx與接收天線ANT_Rx可沿方向D1滑動以達到彼此錯位之功效。此操作可助於使用者進一步微調發射天線ANT_Tx與接收天線ANT_Rx其發射及/或接收輻射波之相位，以求得最佳之發射/接收表現。然而，理論上當兩天線之錯位距離k大於半波長(即0.5λ)，其效應即不再增加，例如當錯位距離k係(0.5λ+5mm)時，其相位調整之效應即理論上近似於錯位距離k係5mm造成之效應，因此第15圖中兩天線之錯位距離k可不需太長。此外，使用者亦可另安裝平行於方向D2之滑軌於發射天線ANT_Tx與接收天線ANT_Rx背後，以於方向D2調整發射天線ANT_Tx與接收天線ANT_Rx彼此之距離，使兩天線可上下錯位。使用者亦可安裝可伸縮套件(如多段式可前後伸縮之套件)於發射天線ANT_Tx及/或接收天線ANT_Rx與背板930之間，以進一步前後伸縮微調發射天線ANT_Tx及/或接收天線ANT_Rx與背板930之間的距離，以使兩天線前後錯位而得到最佳之輻射波接收效果。 Figure 15 is a schematic diagram showing the transmission antenna ANT _Tx and the receiving antenna ANT _Rx being misaligned to each other in the embodiment of the present invention. In the embodiment of FIG. 15, the transmitting antenna ANT _Tx and the receiving antenna ANT _Rx may be separately mounted on the backplane 930 by two sliding rails, so that the transmitting antenna ANT _Tx and the receiving antenna ANT _Rx can slide in the direction D1 to reach each other. The effect of misplacement. This operation can help the user to further fine tune the phase of the transmitting and/or receiving radiation waves of the transmitting antenna ANT _Tx and the receiving antenna ANT _Rx to obtain the best transmission/reception performance. However, theoretically, when the misalignment distance k of the two antennas is greater than half a wavelength (ie, 0.5λ), the effect is no longer increased. For example, when the misalignment distance k is (0.5λ+5mm), the effect of phase adjustment is theoretically similar to The misalignment distance k is an effect caused by 5 mm, so the misalignment distance k of the two antennas in Fig. 15 does not need to be too long. In addition, the user may install another direction parallel to the rail D2 of the transmit antenna and receive antenna ANT _Tx ANT _Rx behind, in the direction D2 to adjust the transmit antenna and the receive antenna ANT _Tx ANT _Rx distance from each other, so that two antennas may be vertically dislocation. The user can also install a retractable kit (such as a multi-stage telescopic package) between the transmitting antenna ANT _Tx and/or the receiving antenna ANT _Rx and the backplane 930 to further flexibly fine-tune the transmitting antenna ANT _Tx and/or receive. The distance between the antenna ANT _Rx and the backplane 930 is such that the two antennas are misaligned before and after to obtain an optimal radiation wave receiving effect.

上述之用以連接反射件與背板、或連接反射柵桿組與背板之連接件(如第2圖之連接件250、第6圖之第一連接件5201與第二連接件5202及第11圖之連接件720)更可包含一伸縮單元(例如以實軸與空心套軸所組成之可伸縮單元；或由具有多個排狀穿孔之第一子連接件與具有多個排狀螺絲孔之第二子連接件組成之可允許長度調整後再以螺絲鎖固之長度可調整的伸縮單元)以使該連接件為長度可沿前後軸向伸縮之連接件，以助於使用者調整反射件與背板之間的距離、或調整反射柵桿組與背板之間的距離以調整第2圖所示之輻射波R01的相位，而求得可將輻射波R11的干擾降至最低的反射件(或反射柵桿組)之位置。本發明實施例中，經實驗得知，當第11至14圖所示之反射柵桿7102其兩兩之間的間距，屬於輻射波波長之0.069倍至0.5倍之間的範圍時，其對輻射波之場形的影響並不顯著，故反射柵桿7102之間距可允許(但不限於)0.065波長至0.5波長(0.065λ~0.5λ)之間，然而大於或小於此範圍之反射柵桿7102的間距，在不嚴重影響輻射波之效率與場形的前提下，均屬本發明之範圍且可供使用。 The connecting member for connecting the reflecting member and the back plate or connecting the reflective grating bar group and the back plate (such as the connecting member 250 of FIG. 2, the first connecting member 5201 and the second connecting member 5202 of FIG. 6 and the The connector 720) of FIG. 11 further includes a telescopic unit (for example, a telescopic unit composed of a solid shaft and a hollow sleeve shaft; or a first sub-connector having a plurality of rows of perforations and a plurality of row screws) The second sub-connecting member of the hole is composed of a telescopic unit which can be adjusted in length after being adjusted by a screw, so that the connecting member is a connecting member whose length can be extended and contracted axially in front and rear to help the user adjust The distance between the reflector and the back plate, or the distance between the reflection grid group and the back plate is adjusted to adjust the phase of the radiation wave R01 shown in FIG. 2, and the interference of the radiation wave R11 can be minimized. The position of the reflector (or reflection grid group). In the embodiment of the present invention, it is experimentally found that when the spacing between the two reflection gratings 7102 shown in FIGS. 11 to 14 is in the range between 0.069 and 0.5 times the wavelength of the radiation wave, The influence of the field shape of the radiation wave is not significant, so the distance between the reflection grids 7102 may allow, but is not limited to, between 0.065 wavelength and 0.5 wavelength (0.065λ~0.5λ), but the reflection grid is larger or smaller than this range. The spacing of 7102 is within the scope of the invention and is available without prejudice to the efficiency and field shape of the radiation wave.

第16圖係本發明實施例中滑軌1610與至少一輔助滑軌1620之示意圖。第16圖所示之滑軌1610係為方向D1(其平行於極化方向)，且至少一輔助滑軌1620係為方向D2(其垂直於極化方向)，其中滑軌1610與輔助滑軌1620可以例如沖壓加工等方式鏤刻製作且互為交錯。如第16圖所示，連接件1650之第一端係以可沿滑軌1610及多個輔助滑軌1620滑動調整之方式，設置於滑軌1610與輔助滑軌1620上，且連接件1650之第二端係設置於上述之反射件(如反射件210)或反射柵桿組(如反射柵桿組8102)，以使本發明中的反射件或反射柵桿組可沿平行於極化方向移動，再沿垂直於極化方向調整至最佳位置。如第16圖所示，連接件1650係先由位置160a移至位置160b，再經微調而移至位置160c。根據本發明另一實施例，如第16圖所示之滑軌1610與多個輔助滑軌1620亦可設置於如第14圖所示之連桿81031上，再將滑軌1610與至少一輔助滑軌1620以滑軌1610可沿方向D1且輔助滑軌1620可沿方向D2滑動調整的方式設置於連接件1650之第一端上，而連接件1650之第二端則可例如設置於天線裝置之背板，進而使反射柵桿組8103可沿平行於極化方向移動，再沿垂直於極化方向調整至最佳位置。當天線裝置具有多個反射件或反射柵桿組時，其可各自於多個輔助滑軌上滑動調整。 Figure 16 is a schematic view of the slide rail 1610 and the at least one auxiliary slide rail 1620 in the embodiment of the present invention. The slide rail 1610 shown in Fig. 16 is in the direction D1 (which is parallel to the polarization direction), and at least one auxiliary slide rail 1620 is in the direction D2 (which is perpendicular to the polarization direction), wherein the slide rail 1610 and the auxiliary slide rail The 1620 can be engraved and interlaced, for example, by stamping or the like. As shown in FIG. 16, the first end of the connecting member 1650 is disposed on the sliding rail 1610 and the auxiliary sliding rail 1620 so as to be slidably adjustable along the sliding rail 1610 and the plurality of auxiliary sliding rails 1620, and the connecting member 1650 The second end is set at The above-mentioned reflective member (such as the reflective member 210) or the reflective grating member group (such as the reflective grating rod group 8102), so that the reflecting member or the reflective grating rod group in the present invention can be moved parallel to the polarization direction, and then perpendicular to The polarization direction is adjusted to the optimal position. As shown in Fig. 16, the connector 1650 is first moved from position 160a to position 160b and then fine tuned to position 160c. According to another embodiment of the present invention, the slide rail 1610 and the plurality of auxiliary slide rails 1620 as shown in FIG. 16 may also be disposed on the link 81031 as shown in FIG. 14, and then the slide rail 1610 and at least one auxiliary. The slide rail 1620 is disposed on the first end of the connecting member 1650 in such a manner that the sliding rail 1610 can be slidably adjusted in the direction D1 and the auxiliary sliding rail 1620 can be adjusted in the direction D2, and the second end of the connecting member 1650 can be disposed, for example, on the antenna device. The backing plate, in turn, allows the reflective grid set 8103 to move parallel to the polarization direction and then adjust to the optimum position perpendicular to the polarization direction. When the antenna device has a plurality of reflectors or groups of reflective grids, they can each be slidably adjusted over a plurality of auxiliary rails.

綜上所述，經採用上述本發明實施例揭露的反射件或反射柵桿組，如第2圖所示發射天線ANT_Tx發出的輻射波R0，其穿過反射件210後的輻射波R1於天線罩200內壁反射產生之輻射波R11，可由反射件或反射柵桿組反射之相位相反且振幅相同的輻射波R01予以減低或消除。因此，有助於接收天線ANT_Rx更正確地接收來自天線裝置200外部之輻射波R3而不受輻射波R11干擾。由於本發明之反射件或反射柵桿組用以供輻射波R0穿透之間隙，其方向D2之長度係大於平行於方向D1之長度(其中方向D2係垂直於方向D1)，故具有極化方向為方向D1之輻射波R0可大部分穿透本發明實施例揭露的反射件或反射柵桿組，而不致過度影響其發射效率，因此本發明實施例揭露的反射件或反射柵桿組其面積可被允許涵蓋發射天線ANT_Tx與接收天線ANT_Rx之開口範圍。此外，本發明揭露之反射件或反射柵桿組其位置係可調整，因此使用者不僅可方便地經調整而求得最佳的反射件或反射柵桿組之位置，亦不需為相異應用開模重製不同版本之天線裝置，而耗費成本。因此，本發明對於改善本領域先前技術之缺失，實有助益。 In summary, the radiation member R0 emitted by the transmitting antenna ANT _Tx according to the embodiment of the present invention is the radiation wave R0 emitted by the transmitting antenna ANT _Tx as shown in FIG. 2, and the radiation wave R1 after passing through the reflecting member 210 is The radiation wave R11 generated by the inner wall of the radome 200 can be reduced or eliminated by the radiation wave R01 having the opposite phase and the same amplitude reflected by the reflector or the reflection grid group. Therefore, it is helpful for the receiving antenna ANT _{Rx to} more correctly receive the radiated wave R3 from the outside of the antenna device 200 without being interfered by the radiated wave R11. Since the reflector or the reflection grid group of the present invention is used for the gap through which the radiation wave R0 penetrates, the length of the direction D2 is greater than the length parallel to the direction D1 (where the direction D2 is perpendicular to the direction D1), so that the polarization The radiation wave R0 having the direction of the direction D1 can penetrate most of the reflector or the reflection grid group disclosed in the embodiments of the present invention without excessively affecting the emission efficiency thereof. Therefore, the reflector or the reflection grid group disclosed in the embodiment of the present invention The area may be allowed to cover the open range of the transmit antenna ANT _Tx and the receive antenna ANT _Rx . In addition, the position of the reflector or the reflection grid group disclosed in the present invention can be adjusted, so that the user can not only conveniently adjust to obtain the position of the best reflector or the reflection grid group, and does not need to be different. It is costly to remanufacture different versions of the antenna device by opening the mold. Thus, the present invention is useful for improving the deficiencies of prior art in the art.
