Embodiment
Figure 1 shows that the structural representation according to the planar dual-direction radiating antenna of one embodiment of the invention, Figure 2 shows that the perspective view according to the planar dual-direction radiating antenna of one embodiment of the invention, referring to Fig. 1 and Fig. 2, planar dual-direction radiating 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.In physical arrangements, substrate 110 comprises a first surface 111 and a second surface 112.Wherein, first surface 111, the second reflecting elements 120 that the first reflecting element 140 is arranged on substrate 110 are arranged on the second surface 112 of substrate 110.In addition, for antenna body 130, the first reflecting element 140 and the second reflecting element 120 all have the arcuation design concaving, and at first surface 111 and second surface 112, form a groove 101 respectively.
With regard to the overall structure of antenna body 130, the second actuator 132 extends from the second reflecting element 120, and therefore the second reflecting element 120 is equivalent to the ground plane (also can regard equivalent system ground as) of antenna body 130.In addition, the first arm 131a of the first actuator 131 and the first arm 132a of the second actuator 132 are overlapped on vertical plane, and the second arm 131b of the first actuator 131 and the second arm 132b of the second actuator 132 are symmetrical in a preset direction DR.
The first reflecting element 140 comprises one first extension 141 and one second extension 142.Wherein, the first extension 141 and the second extension 142 are all arranged on the first surface 111 of substrate 110.In addition, the first extension 141 is arranged in a side of the first arm 131a of the first actuator 131, and the second extension 142 is arranged in the opposite side of the first arm 131a of the first actuator 131.It should be noted that, in the first extension 141 and the second extension 142, there is respectively an end, its place, base near the groove 101 of first surface 111, these both ends are corresponding to the base of the groove 101 on second surface 112 on vertical plane, and position relationship to each other can be configured to be parallel to each other on vertical plane, completely overlapping or partly overlap.More clearly, in practical operation, can be divided into three kinds of mutually corresponding configuration modes: on (1) vertical plane, the base of the groove 101 on first surface 111 can complete matching overlaps the base of the groove 101 on second surface 112; (2), on vertical plane, the base of the groove 101 on first surface 111 exceeds the base of the groove 101 on second surface 112; (3), on vertical plane, the base of the groove 101 on first surface 111 is recessed in the base of the groove 101 on second surface 112.For instance, in the present embodiment, as shown in the perspective view of Fig. 2, the both ends of the first extension 141 and the second extension 142 (that is base of the groove on first surface 111 101) on vertical plane with second surface 112 on the base of groove 101 completely overlapping, therefore the first extension 141 and the second extension 142 are all the arcuation of indent.
The 3rd reflecting element 150 comprises one first covering part 151 and one second covering part 152.Wherein, the first covering part 151 is arranged on the first surface 111 of substrate 110, and with respect to the second arm 131b of the first actuator 131.The second covering part 152 is arranged on the second surface 112 of substrate 110, and with respect to the second arm 132b of the second actuator 132.In addition, the first covering part 151 is electrically connected the first extension 141 of the first reflecting element 140, and the second covering part 152 is electrically connected the second reflecting element 120.
With regard to the overall structure of planar dual-direction radiating antenna 100, as shown in Figure 2, antenna body 130 and the first reflecting element 140 are symmetrical in respectively preset direction DR, and antenna body 130 is arranged in groove 101.In addition, in the present embodiment, the base of groove 101 presents a parabolic shape, and antenna body 130 is positioned near parabolical focus.Moreover the first reflecting element 140 is around the base of groove 101 on vertical plane, the 3rd reflecting element 150 covers the opening of groove 101 on vertical plane.Whereby, the first reflecting element 140, the second reflecting element 120 and the 3rd reflecting element 150 will surround whole antenna body 130 on vertical plane.
Thus, by antenna body 130, given off and towards the electromagnetic energy of the bottom of groove 101, will be first by the first reflecting element 140 and the second reflecting element 120 reflections, 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 is covered by the 3rd reflecting element 150 again, the electromagnetic energy that was therefore originally directed to the opening of groove 101 will be stopped and will again be reflected back.Accordingly, antenna body 130 cannot penetrate electromagnetic energy towards the either direction width that is parallel to substrate 110, so as shown in the schematic perspective view of the substrate 110 of Fig. 3 A, the electromagnetic energy of antenna body 130 leaks out the direction from perpendicular to substrate 110 (namely+z axle with-z axle), so cause planar dual-direction radiating antenna 100 towards the top of substrate 110 (for example :+z axle) with below (for example :-z axle) produce two wave beams.In the above embodiments, its base complete matching for the groove 101 on first surface 111 overlaps the base (configuration mode as shown in Fig. 2 and Fig. 3 A) of the groove 101 on second surface 112, under ideal state, two wave beams are 90 degree with respect to the angle of x-y plane.Further, can be by adjusting groove 101 bases on first surface 111 and the relative position to each other of groove 101 bases on second surface 112 (as mentioned above, the relative position relation that protrudes or inside contract), and changing two wave beams with respect to the corner dimension of x-y plane, its possible application is as detailed below.
It should be noted that, because planar dual-direction radiating antenna 100 has the radiation pattern of two-way (bidirectional), therefore in practical application, planar dual-direction radiating antenna 100 can reduce area and the volume of electronic system, such as: 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 at least must set up two antennas, and wherein an antenna is the wireless signal that receives a relay station, and another antenna is in order to transmit wireless signal to next relay station.Yet, when the planar dual-direction radiating antenna 100 of the present embodiment is applied to microwave relay station, because planar dual-direction radiating antenna 100 can produce two-way radiation pattern, therefore microwave relay station only need set up this kind of antenna, can reach traditional original Transceiver Features, and then effectively simplify the hardware configuration of microwave relay station.
In addition, in the application of tunnel space, owing to being difficult for receiving gps signal or other wireless signals in tunnel, therefore the planar dual-direction radiating antenna 100 of suitable place's configuration the present embodiment that can be in tunnel, therefore can be by the gps signal transmitting by gps signal repeater (relay) or amplifier (amplifier) outside tunnel, the two-port of the sense directly penetrating by planar dual-direction radiating antenna of the present invention institute width (+z and-z direction) towards tunnel transmits gps signal, to reach the function of tunnel signal gain (tunnel booster), wherein+z and-direction of z can be considered the travel direction of vehicle in tunnel simultaneously.Whereby, the vehicle which port enters from tunnel all can all receive gps signal.In other words, the planar dual-direction radiating antenna 100 of the present embodiment also contributes to simplify gps signal and turns the hardware configuration continuing with amplifier station.In the present embodiment, the base of the groove 101 on first surface 111 can complete matching overlaps the base of the groove 101 on second surface 112, under ideal state, the direction of two wave beams (+z and-z) is 90 degree (as shown in Figure 3A) with respect to the angle theta 1 of x-y plane.Further with reference to shown in figure 3B, can be by groove 101 bases and the relative position to each other of groove 101 bases on second surface 112 adjusted on first surface 111, and change the radiation direction (+z or-z) of original wave beam, this wave beam is θ 2 or θ 3 with respect to the angle of x-y plane, wherein θ 2 is less than θ 1, and θ 3 is greater than θ 1.Example with Fig. 3 B: if groove 101 bases on first surface 111, on vertical plane, protrude groove 101 bases on second surface 112, therefore can make the radiation path (+z ') of this wave beam closer to the vehicle travelling in tunnel, receive the effect of gps signal to improve vehicle.Those skilled in the art can comply with above-mentioned adjustment mode certainly, groove on first surface 111 101 bases are inside contracted to groove 101 bases on second surface 112, therefore can produce one with+z ' direction about the radiation beam of+y symmetry (z "); as for the radiation beam of which specific direction of needs, by actual state, determined.
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 to appropriateness to be changed, wherein the 3rd reflecting element can comprise the first covering part 151, the 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 and is less than θ 1 with respect to the angle of x-y plane.If described groove is made to the change of appropriateness with together with relative position between described covering part, just can there is the effect of bidirectional radiation simultaneously.Detailed status of implementation, can, with reference to above-mentioned mode how to adjust groove relative position, no longer describe in detail at this.
In addition, in the application of vehicle bumper systems, planar dual-direction radiating 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 planar dual-direction radiating antenna 100 can scan towards forward and reverse direction simultaneously, therefore only need be by the synthetic wave beam due to electronic signal, radar system just just can reach universe (full-space) and the object that (real-time) scans immediately without the mechanical device that sets up rotable antenna array, and reduces accordingly the hardware configuration of radar system.Further, if the angle from military defense, radar system more hidden close, be more not easy to be found better, the set-up site of radar system namely, may be lower for ground level, or covered by external environment, therefore will certainly be affected in radar signal detecting effect, if but the method for above-mentioned change beam radiation direction is applied in radar system, just can, by different angle of radiation, effectively promote the accuracy rate of radar system.Similarly, for smart-antenna system, the characteristic of the bilateral scanning of planar dual-direction radiating antenna 100 can reduce the quantity of antenna element, and then contribute to the microminiaturization of smart-antenna system and the realization of low priceization.
It is worth mentioning that, planar dual-direction radiating antenna 100 is mainly by the 3rd reflecting element 150, the electromagnetic energy of the opening radiation towards groove 101 to be reflected back.Wherein, the first covering part 151 in the 3rd reflecting element 150 is mainly to reflect the energy that the first actuator 131 gives off towards the opening of groove 101, the second covering part 152 energy that to be mainly reflection the second actuator 132 give off towards the opening of groove 101.Therefore,, in practical application, the length of the first covering part 151 and the second covering part 152 is greater than respectively the second arm 131b of the first actuator 131 and the second arm 132b of the second actuator 132.
