Description
본 발명은 높은 전파복사 전후방비 지향성 안테나에 관한 것으로, 특히 통신에 장애가되는 후방 복사를 방지하도록 한 높은 전파복사 전후방비 지향성 안테나에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a high radiation front and rear directional antenna, and more particularly, to a high radiation front and rear directional antenna which prevents back radiation from obstructing communication.
종래의 안테나는 다이폴소자(D1.D2...Dn D1,D2...Dm)의 후면에 반사판(1)(가령, 금속판, 금속망)만을 부착 사용하는 지향성 안테나이다.Conventional antennas are directional antennas which use only a reflecting plate 1 (for example, a metal plate, a metal mesh) on the rear surface of the dipole elements D1.D2 ... Dn D1, D2 ... Dm.
다이폴소자(D1.D2...Dn D1,D2...Dm)의 복사 패턴은 전방향 즉, 무지향성인데 이 복사 패턴을 단일방향, 즉 지향성으로 만들기 위해 반사판을 후방에 부착시키는 것이다. 이러한 반사판은 일반적으로 금속판이나 금속망으로 만든다.The radiation pattern of the dipole elements (D1.D2 ... Dn D1, D2 ... Dm) is omnidirectional, ie omnidirectional, in which the reflector is attached to the back to make the radiation pattern unidirectional, ie directional. Such reflector plates are generally made of metal plates or metal meshes.
이러한 지향성 안테나는 후방으로 전파가 누설되어 전후방비 30dB이하여서 타통신에 간접 영향을 줄 뿐만아니라 방사 효율도 떨어지게 된다.Such a directional antenna leaks radio waves backwards, so the front and rear ratio is less than 30dB, which not only indirectly affects other communications but also reduces radiation efficiency.
본 발명은 전술한 문제점을 해결하기 위하여 고안된 것으로 일반적인 반사판 측면과 후면에 전파흡수체를 부착시킨 것을 특징으로 한다.The present invention is designed to solve the above problems, characterized in that the radio wave absorber is attached to the side and the back of the general reflector.
이러한 전파흡수체는 안테나의 후방으로 전파가 누설되는 것을 막고 전후방비를 40dB에서 50dB까지 개선한 안테나이다.The radio wave absorber is an antenna that prevents radio waves from leaking to the rear of the antenna and improves the front and rear ratio from 40 dB to 50 dB.

이하에는 첨부한 도면을 이용하여 본 발명의 양호한 실시예에 따른 높은 전파복사 전후방비 지향성 안테나에 대하여 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the high radio wave radiation front and rear directional antenna according to a preferred embodiment of the present invention.
도1은 본 발명 높은 전파복사 전후방비 지향성 안테나의 측면도이다. 도면에서 처럼 반사판(1)위에 전파를 방사하는 다이폴소자(D1.D2...Dn D1,D2...Dm)가 설치되어 있다.1 is a side view of the present invention radio wave front and rear ratio antenna. As shown in the figure, a dipole element (D1.D2 ... Dn D1, D2 ... Dm) for radiating radio waves is provided on the reflecting plate (1).
반사판(1)의 후면에는 본 발명 높은 전파복사 전후방비 지향성 안테나의 특기할 만한 사항으로 전파를 흡수하는 전파흡수체(3)(가령, 패라이트, 탄소)가 부착되어 있다. 전파흡수체(3)의 후면은 금속판커버(4)로 씨워져 있으며 그 상단위에서 안테나 전방으로 비와 눈과 같은 기후에 견딜 수 있도록 방설커버(2)로 덮여있다.On the rear surface of the reflector 1, a radio wave absorber 3 (e.g., a ferrite, carbon), which absorbs radio waves, is attached to the present invention. The rear surface of the radio wave absorber 3 is covered with a metal plate cover 4 and covered with a snow cover 2 so as to withstand weather such as rain and snow from above the antenna.
위와같은 구성을 한 본 발명 높은 전파복사 전후방비 지향성 안테나는 무선 주파수 송신기 또는 수신기를 본 안테나 커넥터(5)에 고주파 급전선으로 연결하고, 이를 통해 들어온 급전선 고주파 신호를 금속커버(4)와 전파흡수체(3)를 통과 시킨 후 고주파분배기에서 안테나 다이폴소자(D1.D2...Dn D1,D2...Dm) 숫자만큼 분배하여 급전선을 통하여 복사패턴에 따라 위상 조정 후 각각의 다이폴 안테나 소자(D1.D2...Dn D1,D2...Dm)에 급전 하는 동작을 한다. 이렇게 다이폴안테나에서 복사된 전파는 전방향으로 복사되고, 반사판(1)에서 재반사하여 전방향으로 합성 증가하여 복사된다. 그러나 복사된 전파의 일부는 반사판(1) 뒤로 누설되어 뒷부분으로 미약한 전파를 복사하여 타통신에 장애를 준다.In the present invention, the radio wave front and rear non-directional directional antenna having the configuration described above connects a radio frequency transmitter or receiver to the antenna connector 5 with a high frequency feed line, and the feed line high frequency signal received through the metal cover 4 and the radio wave absorber ( 3) After passing through, divide the antenna dipole elements (D1.D2 ... Dn D1, D2 ... Dm) by high frequency divider and adjust the phase according to the radiation pattern through feeder line. D2 ... Dn D1, D2 ... Dm) is energized. The radio waves radiated from the dipole antenna are radiated in all directions, and are reflected back from the reflector 1 and synthesized in all directions and radiated. However, part of the radiated radio waves leaks behind the reflector 1 and radiates weak radio waves to the rear part, thereby impairing other communication.
이를 방지하기 위하여 전파흡수체(3)를 부착하여 미약전파를 재차 흡수하고 또 금속판커버(4) 차폐하에 후방 복사를 대폭 축소한 안테나이다.In order to prevent this, the radio wave absorber (3) is attached to absorb the weak radio wave again, and the antenna is greatly reduced rear radiation under the shield of the metal plate cover (4).
도 2는 본 발명 높은 전파복사 전후방비 지향성 안테나의 정면도인데 안테나의 다이폴소자(D1.D2...Dn D1,D2...Dm)의 배열과 반사판의 접합크기를 보여주고 있다.FIG. 2 is a front view of the high-radiation radiation-front / directional antenna of the present invention, which shows the arrangement of the dipole elements (D1.D2 ... Dn D1, D2 ... Dm) of the antenna and the junction size of the reflector.
도 3는 본 발명 높은 전파복사 전후장비 지향성 안테나의 단면도이다. 도면에서 볼 수 있듯이 도1에서 설명한 바와 같은 구성으로 되어 있다.Figure 3 is a cross-sectional view of a high-frequency radiation front and rear equipment directional antenna of the present invention. As can be seen from the figure, it has a configuration as described in FIG.
도 4는 본 발명의 실시예이다. 도면에서 볼 수 있듯이 본 발명은 다이폴 소자(D1.D2...Dn D1,D2...Dm)가 n이나 m개로 구성될 수 있다..4 is an embodiment of the present invention. As can be seen in the drawing, the present invention may be configured with n or m dipole elements (D1. D2... Dn D1, D2 ...
본 발명 높은 전파복사 전후방비 지향성 안테나는 전술한 실시예에 국한되지 않고 본 발명의 기술 사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수가 있다.The present invention is not limited to the above-described radio wave radiation front and rear directional antennas can be modified in various ways within the scope of the technical idea of the present invention.
이상에서 설명한 본 발명 높은 전파복사 전후방비 지향성 안테나는 송 수신기의 전파 방사와 흡수시에 반사판 후면으로 미약한 전파가 누설되는 것을 방지하여 종래 지향성 안테나 전후방비가 30dB 이하인 것을 40dB∼50dB이상 개선한 전파간섭을 제거하여 타통신에 장애를 주지않으며 높은 지향성을 얻는 효과가 있다.The radio wave front and rear ratio directional antenna of the present invention described above prevents weak radio waves from leaking to the rear surface of the reflector during radio wave radiation and absorption of the transmitter and receiver. It is effective to get high directivity without disturbing other communication by eliminating the problem.
