For example, by forming a zigzag conductive pattern to have a sufficient length, the first radiator 600 may be implemented to receive a signal in the AM / FM band. In particular, since the AM band is a low band, it may be preferable that the first radiator 600 is formed to have a sufficient length.
한편, 제2 방사체부(140)에는 제2 방사체(200)가 형성될 수 있다. 제2 방사체는 V2V(Vehicle-to-Vehicle), 즉 차량 간 통신을 위해 구현되는 안테나 방사체일 수 있다. 차량 간 통신에 사용 되는 주파수 대역은 AM 대역에 비해 높은 주파수를 사용하므로, 제2 방사체(200)는 제1 방사체(600)에 비해 작은 크기를 가질 수 있다. 특히, 도 2에 도시된 바와 같이 제2 방사체(200)는 제2 방사체부(140)의 커버와 인접한 부분에 형성되어, 제1 방사체(600)가 형성되는 제1 방사체부(120)와 가장 먼 거리를 갖는 위치에 형성될 수 있다. 즉, 제1 방사체(600)가 회로기판(10)의 일측면에 인접한 위치에 형성된다면, 제2 방사체(200)는 회로기판(10)의 타측면에 인접한 위치에 형성됨으로 제2 방사체(200)는 제1 방사체(600)와 가장 먼 거리를 같는 위치에 형성될 수 있다. 또한, 제2 방사체(200)는 제1 방사체(600)와 멀어지는 방향으로 연장되어 형성될 수 있는데, 도 1 및 도 4에 도시된 바와 같이 회로기판(10)의 제2 방사체부(120)가 샤크 핀 형상의 커버(500)에 밀착되어 제1 방사체(600)와 멀어지는 방향으로 연장되어 형성되고, 제2 방사체(200)는 제2 방사체부(120)의 연장 방향을 따라 연장되어 형성됨으로 제2 방사체(200)는 제1 방사체(600)와 멀어지는 방향으로 연장되어 형성될 수 있다.Meanwhile, the second radiator 200 may be formed in the second radiator unit 140. The second radiator may be a vehicle-to-vehicle (V2V), that is, an antenna radiator implemented for inter-vehicle communication. Since the frequency band used for the vehicle-to-vehicle communication uses a higher frequency than the AM band, the second radiator 200 may have a smaller size than the first radiator 600. In particular, as shown in FIG. 2, the second radiator 200 is formed at a portion adjacent to the cover of the second radiator portion 140 to most closely match the first radiator portion 120 on which the first radiator 600 is formed. It may be formed at a location having a long distance. That is, if the first radiator 600 is formed at a position adjacent to one side of the circuit board 10, the second radiator 200 is formed at a position adjacent to the other side of the circuit board 10 and thus the second radiator 200. ) May be formed at a position equal to the longest distance with the first radiator 600. In addition, the second radiator 200 may extend in a direction away from the first radiator 600. As shown in FIGS. 1 and 4, the second radiator portion 120 of the circuit board 10 may be formed. The second radiator 200 is formed to extend in a direction away from the first radiator 600 by being in close contact with the shark pin-shaped cover 500, and the second radiator 200 extends along the extending direction of the second radiator unit 120. The second radiator 200 may extend in a direction away from the first radiator 600.
설명한 바와 같이, 차량 간 통신을 위해 구현되는 제2 방사체(200)는 제1 방사체(600)와 동일한 회로기판(10)에 형성되지만, 제2 방사체(200)는 제1 방사체(600)와 먼 거리를 갖는 위치에 형성되거나, 제2 방사체(200)는 제1 방사체(600)와 멀어지는 방향으로 연장되어 형성되므로 제1 방사체(600)와 제2 방사체(200)의 격리도가 확보될 수 있다.As described, the second radiator 200 implemented for inter-vehicle communication is formed on the same circuit board 10 as the first radiator 600, but the second radiator 200 is far from the first radiator 600. The second radiator 200 may be formed at a position having a distance, or the second radiator 200 may extend in a direction away from the first radiator 600, so that a degree of isolation between the first radiator 600 and the second radiator 200 may be secured.
또한, 회로기판(100)의 제2 방사체(200)와 제1 방사체(600)의 사이에는 슬릿(110)이 형성된다. 회로기판(100)에 형성된 슬릿(110)으로 인해 제1 방사체(600)와 제2 방사체(200)의 격리도는 더욱 향상될 수 있다.In addition, a slit 110 is formed between the second radiator 200 and the first radiator 600 of the circuit board 100. Due to the slit 110 formed in the circuit board 100, the isolation between the first radiator 600 and the second radiator 200 may be further improved.
도 6은 본 발명의 다른 실시예에 따른 차량용 안테나의 회로 기판의 평면도를 도시한 도면이다.6 is a plan view of a circuit board of a vehicle antenna according to another exemplary embodiment of the present disclosure.
도 6을 참조하면, 본 발명의 다른 실시예에 따른 차량용 안테나의 회로 기판은 샤크 핀 형상의 커버(500)에 밀착되지 않으며, 제2 방사체부(120)가 제1 방사체(600)와 멀어지는 방향으로 연장되어 형성되지 않는다. 본 발명의 다른 실시예에 따른 차량용 안테나 또한 회로기판(10)에 형성된 슬릿(110)으로 인해 제1 방사체(600)와 제2 방사체(200)의 격리도를 어느 정도 확보할 수 있게 된다.Referring to FIG. 6, the circuit board of the vehicle antenna according to another embodiment of the present invention is not in close contact with the shark fin-shaped cover 500, and the second radiator 120 is moved away from the first radiator 600. It does not extend to form. The vehicle antenna according to another exemplary embodiment of the present invention may also secure a degree of isolation between the first radiator 600 and the second radiator 200 due to the slit 110 formed on the circuit board 10.

Compared to a vehicle antenna according to another exemplary embodiment, the second radiator 120 may extend in a direction away from the first radiator 600, and the second radiator 200 may be further from the first radiator 600. It can be located on the street. Therefore, the vehicle antenna according to the preferred embodiment of the present invention can ensure more isolation than the vehicle antenna according to another embodiment of the present invention shown in FIG. 6.
상술한 바와 같이, 본 발명의 바람직한 일 실시예에 따른 차량용 안테나는 하나의 회로기판(10)에 AM/FM 대역의 신호를 수신하는 제1 방사체(미도시)와 V2V(Vehicle-to-Vehicle), 즉 차량 간 통신을 위한 제2 방사체(200)를 형성하여 제작 비용을 절감할수 있으며, 각 방사체의 격리도 역시 확보할 수 있게 된다. As described above, a vehicle antenna according to an exemplary embodiment of the present invention includes a first radiator (not shown) and a vehicle-to-vehicle (V2V) that receive signals in an AM / FM band on one circuit board 10. That is, the manufacturing cost can be reduced by forming the second radiator 200 for communication between vehicles, and the isolation of each radiator can also be secured.
