Claims (1)
- 전면덮개에 설치되며 위성안테나에 집속된 원편파를 90°위상차를 갖는 수평 및 수직편파로 변환하는 피드혼과, 후면 덮개의 후방측으로 돌출되며 상기 피드혼의 동일 축상에 마련되는 반사판과, 전, 후면 덮개 사이에 배치되며 피드혼의 도파로 직경과 반사판의 직경에 일치하는 원형의 그라운드 패턴이 프린트되고 상기 원형그라운드 패턴내에 90°각도차를 갖는 제1,2입력 프로브가 프린트되는 LNB회로기판을 포함하는 수평 및 수직편파 신호 공용 수신용 LNB에 있어서, 상기 반사판의 내부에 상기 제1,2입력 프로브중 어느 하나와 평행하게 반사막대를 설치하여 두 편파신호에 대한 반사파의 @ 길이 사이에 편차가 발생되게 구성한다.※참고사항:최초출원 내용에 의하여 공개되는 것임.
