Embodiment
Figure 1 shows that structural representation according to the plane bidirectional radiation antenna of one embodiment of the invention, Figure 2 shows that perspective view according to the plane bidirectional radiation antenna of one embodiment of the invention, please be simultaneously with reference to Fig. 1 and Fig. 2, plane bidirectional radiation antenna 100 comprises a substrate 110, one first reflecting element 140, an antenna body 130, one second reflecting element 120 and one the 3rd reflecting element 150.On physical arrangements, substrate 110 comprises a first surface 111 and a second surface 112.Wherein, first reflecting element 140 first surface 111, the second reflecting elements 120 that are arranged on substrate 110 are arranged on the second surface 112 of substrate 110.In addition, for antenna body 130, first reflecting element 140 and second reflecting element 120 all have the arcuation design that concaves, and form a groove 101 at first surface 111 and second surface 112 respectively.
With regard to the overall structure of antenna body 130, second actuator 132 extends from second reflecting element 120, and therefore second reflecting element 120 is equivalent to the ground plane (also can regard the system ground of equivalence as) of antenna body 130.In addition, the first arm 132a of the first arm 131a of first actuator 131 and second actuator 132 is overlapped on vertical plane, and the second arm 132b of the second arm 131b of first actuator 131 and second actuator 132 is symmetrical in a preset direction DR.
First reflecting element 140 comprises one first extension 141 and one second extension 142.Wherein, first extension 141 and second extension 142 all are arranged on the first surface 111 of substrate 110.In addition, first extension 141 is arranged in the side of the first arm 131a of first actuator 131, and second extension 142 is arranged in the opposite side of the first arm 131a of first actuator 131.It should be noted that, in first extension 141 and second extension 142, has an end respectively, it is near the place, base of the groove 101 of first surface 111, these both ends on the vertical plane corresponding to the base of the groove on the second surface 112 101, position to each other close tie up to can be configured on the vertical plane be parallel to each other, overlapping fully or overlap.More clearly, can be divided into three kinds of corresponding mutually configuration modes in the practical operation: on (1) vertical plane, but the base complete matching of the groove 101 on the first surface 111 overlaps the base of the groove 101 on the second surface 112; (2) on the vertical plane, the base of the groove 101 on the first surface 111 exceeds the base of the groove 101 on the second surface 112; (3) on the vertical plane, the base of the groove 101 on the first surface 111 is recessed in the base of the groove 101 on the second surface 112.For instance, in the present embodiment, shown in the perspective view of Fig. 2, the both ends of first extension 141 and second extension 142 (that is base of the groove on the first surface 111 101) on the vertical plane with second surface 112 on the base of groove 101 overlapping fully, therefore first extension 141 and second extension 142 all are the arcuation of indent.
The 3rd reflecting element 150 comprises one first covering part 151 and one second covering part 152.Wherein, first covering part 151 is arranged on the first surface 111 of substrate 110, and with respect to the second arm 131b of first actuator 131.Second covering part 152 is arranged on the second surface 112 of substrate 110, and with respect to the second arm 132b of second actuator 132.In addition, first covering part 151 electrically connects first extension 141 of first reflecting element 140, and second covering part 152 electrically connects second reflecting element 120.
With regard to the overall structure of plane bidirectional radiation antenna 100, as shown in Figure 2, the antenna body 130 and first reflecting element 140 are symmetrical in preset direction DR respectively, and antenna body 130 is arranged in the groove 101.In addition, in the present embodiment, the base of groove 101 presents a parabolic shape, and antenna body 130 promptly is positioned near the parabolic focus.Moreover around the base of groove 101, the 3rd reflecting element 150 then covers the opening of groove 101 to first reflecting element 140 on vertical plane on vertical plane.Whereby, first reflecting element 140, second reflecting element 120 and the 3rd reflecting element 150 will surround entire antenna body 130 on vertical plane.
Thus, given off and towards the electromagnetic energy of the bottom of groove 101 by antenna body 130, will be earlier by first reflecting element 140 and 120 reflections of second reflecting element, and then the electromagnetic energy of the bottom of radiation direction groove 101 is directed to the opening of groove 101.Yet because the opening of groove 101 covers by the 3rd reflecting element 150 again, the electromagnetic energy that therefore originally was directed to the opening of groove 101 will be stopped and again be reflected.In view of the above, antenna body 130 can't penetrate electromagnetic energy towards the either direction width of cloth that is parallel to substrate 110, so shown in the schematic perspective view of the substrate 110 of Fig. 3 A, the electromagnetic energy of antenna body 130 will be from leaking out perpendicular to the direction of substrate 110 (just+z axle and-z axle), so cause plane bidirectional radiation antenna 100 towards the top of substrate 110 (for example :+z axle) with the below (for example :-z axle) produce two wave beams.In the above embodiments, its base complete matching for the groove 101 on the first surface 111 overlaps the base (configuration mode shown in Fig. 2 and Fig. 3 A) of the groove 101 on the second surface 112, under the ideal state, two wave beams are 90 degree with respect to the angle on x-y plane.Further, can be by adjusting groove 101 bases on the first surface 111 and the groove 101 bases relative position to each other on the second surface 112 (as mentioned above, protrude or in the relative position relation that contracts), and changing the corner dimension of two wave beams with respect to the x-y plane, its possible application is as detailed below.
It should be noted that, because plane bidirectional radiation antenna 100 has the radiation pattern of two-way (bidirectional), so in practical application, plane bidirectional radiation antenna 100 can reduce the area and the volume of electronic system, for example: vehicle bumper systems (vehicular anti-collision system), microwave relay station (microwave relay station), smart-antenna system (smart antenna system) and radar system (RADAR system) etc.
For instance, general microwave relay station must set up two antennas at least, and wherein an antenna is in order to receiving the wireless signal of a last relay station, and another antenna is then given next relay station in order to transmit wireless signal.Yet, when the plane of present embodiment bidirectional radiation antenna 100 is applied to microwave relay station, because plane bidirectional radiation antenna 100 can produce two-way radiation pattern, so microwave relay station only need set up this kind of antenna and can reach traditional original Transceiver Features, and then simplifies the hardware configuration of microwave relay station effectively.
In addition, in the application of tunnel space, owing to be difficult for receiving gps signal or other wireless signals in the tunnel, so plane bidirectional radiation antenna 100 of appropriate location that can be in tunnel configuration present embodiment, so can be with the gps signal that is transmitted by gps signal repeater (relay) or amplifier (amplifier) outside the tunnel, directly the two-port of the sense that penetrates by the plane of the present invention bidirectional radiation antenna institute width of cloth (+z and-z direction) towards the tunnel transmits gps signal, to reach the function of tunnel signal gain (tunnel booster).Whereby, the vehicle which port enters from the tunnel all can all receive gps signal.In other words, the plane bidirectional radiation antenna 100 of present embodiment also helps to simplify gps signal changes the hardware configuration that continues with amplifier station.In the present embodiment, but the base complete matching of the groove 101 on the first surface 111 overlaps the base of the groove 101 on the second surface 112, under the ideal state, the direction of two wave beams (+z and-z) be 90 degree (as shown in Figure 3A) with respect to the angle theta 1 on x-y plane.Further, can be by groove 101 bases on the adjustment first surface 111 and the groove 101 bases relative position to each other on the second surface 112, and change arbitrary wave beam radiation direction (+z or-z), this wave beam is θ 2 with respect to the angle on x-y plane, wherein θ 2 is less than θ 1.Example with Fig. 3 B: if groove 101 bases on the first surface 111, contract on vertical plane groove 101 bases on second surface 112, so can make the radiation path (+z ') of this wave beam more approach to travel vehicle in the tunnel, to improve the effect that vehicle receives gps signal.Those skilled in the art can comply with above-mentioned adjustment mode certainly, with groove 101 bases of protrusion on second surface 112,101 bases of the groove on the first surface 111, one be symmetrical in+radiation beam of z ' direction (z ') so can produce, which, then decide by actual state as for the radiation beam of needs specific direction.
In the same manner, those skilled in the art also can comply with above-mentioned adjustment mode, the ornaments mode of the 3rd reflecting element is made appropriateness ground to be changed, wherein the 3rd reflecting element can comprise first covering part 151, second covering part 152, the 3rd covering part 410 and the 4th covering part 420, can change the radiation direction of above-mentioned arbitrary wave beam equally, wherein this wave beam is executed less than θ 1 with respect to the angle on x-y plane.As if the change of the relative position of described groove between described covering part being made appropriateness, just can have the effect of bidirectional radiation simultaneously.Detailed enforcement situation then can then no longer describe in detail at this with reference to above-mentioned mode how to adjust the groove relative position.
In addition, in the application of vehicle bumper systems, plane bidirectional radiation antenna 100 can detect vehicle in advancing and the spacing between the both sides' vehicle of front and back simultaneously, and then effectively reduces the hardware configuration of vehicle bumper systems.In addition, in the application of array antenna, radar system for example, because plane bidirectional radiation antenna 100 can scan towards positive and negative two directions simultaneously, so only need the synthetic wave beam due to the electronic signal, the mechanical device that radar system just need not to set up the rotable antenna array just can reach the purpose of universe (full-space) and instant (real-time) scanning, and reduces the hardware configuration of radar system in view of the above.Further, if angle from military defense, radar system more latent close, more be not easy to be found better, just radar system the place is set, may be lower for ground level, or covered by external environment, so on radar signal detecting effect, will certainly be affected, but, just can promote the accuracy rate of radar system effectively by different angle of radiation if the method for above-mentioned change beam radiation direction is applied in the radar system.Similarly, for smart-antenna system, the characteristic of the bilateral scanning of plane bidirectional radiation antenna 100 can reduce the quantity of antenna element, and then help the microminiaturization of smart-antenna system and the realization of low priceization.
What deserves to be mentioned is that plane bidirectional radiation antenna 100 mainly is will to reflect back towards the electromagnetic energy of the opening radiation of groove 101 by the 3rd reflecting element 150.Wherein, first covering part 151 in the 3rd reflecting element 150 mainly is in order to reflecting the energy that opening gave off of first actuator 131 towards groove 101, and second covering part 152 then mainly is the energy that opening gave off of reflection second actuator 132 towards groove 101.Therefore, in practical application, the length of first covering part 151 and second covering part 152 is respectively greater than second arm 131b of first actuator 131 and the second arm 132b of second actuator 132.
In addition, in practical application, also the ability that covering part is strengthened the 3rd reflecting element 150 block electromagnetic energy can be set additionally.For instance, Figure 4 shows that structural representation according to the plane bidirectional radiation antenna of another embodiment of the present invention, with under embodiment shown in Figure 2 compares, the 3rd reflecting element 150 ' shown in Fig. 4 embodiment also comprises one the 3rd covering part 410 and one the 4th covering part 420 with Fig. 1.As shown in Figure 4, the 3rd covering part 410 is arranged on the first surface 111 of substrate 110, and overlapped with second covering part 152 on vertical plane.In addition, the 4th covering part 420 is arranged on the second surface 112 of substrate 110, and overlapped with first covering part 151 on vertical plane.
Thus, first actuator 131 on the first surface 111 will be subjected to the encirclement of first covering part 151, the 3rd covering part 410 and first reflecting element 140, and second actuator 132 on the second surface 112 will be subjected to the encirclement of second covering part 152, the 4th covering part 420 and second reflecting element 120.Whereby, first reflecting element 140, second reflecting element 120 and the 3rd reflecting element 150 will further increase the directive property of plane bidirectional radiation antenna 400 on vertical substrate 110 directions.It should be noted that, in practical application, the 3rd covering part 410 and the 4th covering part 420 are set simultaneously, or the 3rd covering part 410 and the 4th covering part 420 select a setting, can reach the function of strengthening the block electromagnetic energy, so this area has and knows that usually the knowledgeable can be according to the design configuration structure of change the 3rd reflecting element 150 ' arbitrarily.
Moreover plane bidirectional radiation antenna 100 also can be arranged in pairs or groups guide hole (via) to utilize the characteristic that just promotes reflecting element of its metallic character.For instance, Figure 5 shows that perspective view according to the plane bidirectional radiation antenna of yet another embodiment of the invention, compared to Fig. 1 and embodiment shown in Figure 2, plane bidirectional radiation antenna 500 shown in Fig. 5 embodiment also comprises a plurality of first guide holes, for example: first guide hole 511～516, and a plurality of second guide holes, for example: second guide hole 521～522.Wherein, first guide hole 511～513 runs through second reflecting element 120, substrate 110 and first extension 141, and first guide hole 514～516 runs through second reflecting element 120, substrate 110 and second extension 142.Whereby, first reflecting element 140 can be electrical connected by first guide hole 511～516 and second reflecting element 120.In addition, second guide hole 521～522 runs through first covering part 151, substrate 110 and second covering part 152, is electrical connected to cause first covering part 151 and second covering part 152.Thus, the lifting along with the characteristic of reflecting element can relatively improve the directive property of plane bidirectional radiation antenna 500 on vertical substrate 110 directions.In addition, when utilizing guide hole to promote the characteristic of reflecting element, also can as shown in Figure 4 the ability that covering part is strengthened the 3rd reflecting element 150 ' block electromagnetic energy be set additionally.
Further, in the various embodiments described above, the base of groove 101 all presents a parabolic shape.Yet in practical application, the shape on the base of groove 101 is not as limit, and its shape also can be arcuation, wavy or polyline shaped.For instance, Figure 6 shows that perspective view according to the plane bidirectional radiation antenna of further embodiment of this invention, compared to Fig. 1 and embodiment shown in Figure 2, both are main difference, for plane bidirectional radiation antenna 600, the shape on the base of formed groove 101 ' in first reflecting element 140 ', and the shape on the base of formed groove 101 ' in second reflecting element 120 '.As shown in Figure 6, correspond to the adaptive adjustment of the indent radian of first reflecting element 140 ' and second reflecting element 120 ', the base of groove 101 ' also presents polyline shaped.
On the other hand, in the various embodiments described above, the configuration of first reflecting element 140 is the layout on a plane, but the designer can do corresponding area adjustment according to design.For instance, Figure 7 shows that the perspective view according to the plane bidirectional radiation antenna of further embodiment of this invention, compared to Fig. 1 and embodiment shown in Figure 2, both are main difference, first reflecting element 140 " layout area and shape.At this, as shown in Figure 7, first reflecting element 140 " can regard planar metal bar (metal strips) as but not original metal covering (plane).Whereby, plane bidirectional radiation antenna 700 can reduce accordingly at the layout area of the first surface 111 of substrate 110, and then help the development of the microminiaturization of plane bidirectional radiation antenna 700.
In sum, the present invention is a mode of utilizing first reflecting element, second reflecting element, the 3rd reflecting element to surround antenna body on vertical plane, cause the electromagnetic energy of antenna change from perpendicular to the direction of substrate but not the direction that is parallel to substrate leak out.Thus, plane bidirectional radiation antenna can produce two wave beams simultaneously towards the top and the below of substrate, and then form the characteristic of bidirectional radiation.Relatively, in practical application, the bidirectional radiation field pattern that plane bidirectional radiation antenna is possessed will help to reduce the hardware configuration of electronic system, and then help the development of the microminiaturization of electronic system.
Though the present invention with embodiment openly as above; right its is not in order to limit the present invention; have in the technical field under any and know the knowledgeable usually; without departing from the spirit and scope of the present invention; when doing a little change and retouching, so protection scope of the present invention is as the criterion when looking claims person of defining.
