Abstract
위성을 이용한 양방향 멀티미디어 통신용 이동 안테나 시스템에서, 이동 환경 조건하에 국제적인 안테나 패턴 규격을 만족하는 배열 안테나를 설계 및 제작하였다. 이동 안테나 시스템에서 적용된 배열 안테나는 소파 구조로, 유전자 알고리즘을 이용하여 최적의 저부엽 특성을 갖는 비균등 간격으로 부배열 안테나의 위치를 설정하였다. 부배열 안테나는 송수신 겸용의 3중 적층구조 마이크로스트립 패치 안테나로, 안테나 이득 및 대역폭 특성을 개선하였다. 본 논문에서는 설계된 부배열 안테나 및 유전자 알고리즘이 적용된 부배열 간의 간격 특성과 제작된 부배열 안테나 및 이동 안테나 시스템을 통해 결과를 살펴보았다.
