Abstract
본 논문에서는 위성통신용 송/수신 안테나 시스템을 위한 배열 안테나를 설계하고 이를 제작하여 그 결과플 검증한다. 본 논문에 제시된 안테나는 하나의 마이크로스트립 패치 소자로 송/수신을 겸용하기 위하여 광대역 특성을 가지며 , 힘수신 주피수 대역에서 각각 우원편파와 죠 } 왼편파로 장 4 하도록 설계하였다 . 특히 광대역 특성을 얻기 위해 적층 기술을 이용하였고, 원형편파 생성을 위해 truncated square 형태의 정사각형 소자를 이용하였으며, 2xl 시퀄셜 로테이션 배열 방식을 적용하여 대역폭 특성을 더욱 개선시켰다. 설계 결고결과에 대한 타당성을 검증하기 위하여 8xl 마이크로스트렵 배열 안테나를 제작 및 측정하여 시뮬레이션 결과와 비교하였으며, 측정결과는 시뮬레이 션 결과 와 거의 일치함을 보였다.
