Abstract

도파관 형태의 혼 안테나와 결합하며, 선형 편파 신호와 원형 편파 신호 간 상호 변환하기 위한 편파 변환기능과 도파관 신호를 외부 선로 신호로 변환하기 위한 어댑터 기능을 하나의 도파관 어댑터로 구현함으로써, 원형 편파 통신 시스템의 구성을 단순화하고 소형화할 수 있는 원형 편파 발생이 가능한 도파관 어댑터가 개시된다. 개시된 원형 편파 발생기능을 가지는 도파관 어댑터는, 시스템에서 외부 선로를 통해 전달받은 신호를 도파관 전송선로로 전달하기 위한 프루브(probe)와; 프루브 후방에 수직 편파 신호를 수평 편파신호로 변환하기 위한 편파변환 선로반사기와; 후방 신호를 전방으로 보내기 위한 백숏(backshort)으로 도파관 어댑터를 구현함으로써, 인공위성 통신용을 비롯한 원형 편파를 사용하는 모든 통신 시스템에서의 원형 편파 신호 발생 기능과 신호 연결이 가능하다.
