Abstract

본 발명은 직선편과 뿐만아니라 원형편파까지 선별하여 수신할 수 있으며, 이러한 다중편파를 수신하기 위한 장치가 간단한 구조로 이루어지게 함으로써 제조가 용이하고 제작비용을 낮출 수 있는 다중 편파수신이 가능한 위성안테나용 수신컨버터에 관한 것으로, 위성신호의 전파를 정보수신장치로 전달하기 위한 위성안테나용 수신컨버터에 있어서, 주파수를 소정치로 다운시키는 메인회로가 내부에 구비된 LNB(31)와, 상기 LNB의 일측에 구비되어 위성으로 부터의 신호를 수신하기 위한 도파관(32)과, 상기 도포관의 내경면에 설치되는 것으로서 원주방향으로 소정각도 이격되고 반경방향으로 입설된 제1 및 제2 공진프로브(34)(35)와, 상기 제1 및 제2 공진프로브를 LNB의 메인회로에 각각 연결하기 위한 것으로서 직선편파 및 원형편파를 선별할 수 있도록 서로 다른 길이를 갖는 제1 내지 제4 전송선(51)-(54)과, 상기 제1 및 제2 공진프로브와 제1 내지 제4 전송선 사이에 구비하여 하나이상의 전송선과 선택적으로 연결되게 함으로써 특정한 편파신호를 선택하기 위한 스위칭부(60)를 구성하여 된 것이다.The present invention can select and receive not only linear polarization but also circular polarization, and the antenna for receiving such multiple polarizations has a simple structure, making it easy to manufacture and lowering the manufacturing cost. A reception converter for a satellite antenna for transmitting a radio wave of a satellite signal to an information receiving device, comprising: an LNB 31 having a main circuit therein for lowering a frequency to a predetermined value; Waveguide 32 for receiving a signal from the satellite and provided on one side, and the first and second resonant probes 34 which are installed in the inner diameter surface of the coating tube spaced at a predetermined angle in the circumferential direction and placed in the radial direction 35) and the first and second resonant probes, respectively, for connecting the LNB main circuit so as to discriminate linear and circular polarizations. Specific polarization by selectively connecting the first to fourth transmission lines 51 to 54 with different lengths, and between the first and second resonant probes and the first to fourth transmission lines, and selectively connecting one or more transmission lines. The switch 60 is configured to select a signal.
