Abstract
본 발명은 이중 원편과 수신장치에 관한 것으로, 위성방송 수신 안테나의 피드혼(10) 후단에는 페치안테나(11)가 중앙에 구비된 유전체판(12)으로 이루어진 안테나 인쇄회로기판(13)이 직접 접합되고, 상기 페치 안테나(11)의 후단면에는 신호결합용 십자 슬롯(14)이 중앙에 구비된 접지판(15)이 접합되는 한편, 상기 접지판(15)의 후단면에는 상기 십자 슬롯(14)과 4개의 교차점(A,B,C,D)을 이루어 우선, 좌선 원편파를 분리 전송하는 마이크로스트립 전송선(16)가 구비된 유전체판(17)으로 이루어진 LNB인쇄회로기판(18)이 접합된 구조로 되어, 그 구성이 간단할 뿐만 아니라, 방송위성으로부터 송신된 이중 원평파를 좌선, 우선 원편파 신호로 각각 분리하여 동시에 수신할 수 있는 것이다.
Description
