- W4236048519 abstract "본 논문에서는 정밀 포탄의 자탄용 센서에 적용 가능한 경량형 W-대역 카세그레인 반사경 안테나를 설계, 제작, 측정하였다. 이중 모드 피드 혼, 부 반사경 및 주반경으로 구성된 카세그레인 반사경 안테나를 최적 설계하였다. 폴리카보네이트 플라스틱 재료를 사용하여 주 반사경, 부 반사경－레이돔 몸체를 사출 성형으로 제작한 후 반사면을 PVD 공법으로 도금함으로써 경량화된 안테나를 구현하였다. 피드 혼은 알루미늄 블록을 정밀 가공하여 제작하였다. 제작품을 측정한 결과 제안한 안테나는 1.2%의 대역폭에서 -16dB 이하의 반사계수, 중심 주파수에서 1.8°의 빔폭과 38.6dBi의 이득을 가짐을 확인하였다." @default.
