Abstract

In this paper, we proposed and implemented a novel antenna cover mounted over a microstrip path antenna for ultrafast aircraft. A protective antenna cover prevents alteration in the electrical characteristics of the antenna due to environmental conditions. The permittivity of the cover materials should be practically invariable at all operating frequencies. We evaluated the characteristics of the antenna with both simulation and experiment. The experimental results show that the proposed antenna cover can be useful for ultrafast aircraft.

본 논문은 고속 비행체용 안테나를 보호하기 위해 사용되는 안테나 커버(cover)를 새로운 제조 방식으로 제작하여 시뮬레이션과 실험을 통해 성능을 평가하였다. 안테나 커버용 소재는 사용 환경인 $600^{\circ}C$ 이상의 온도와 구조적 안정성을 가져야할 뿐만 아니라, 전파 투과성이 우수한 저유전율 소재여야만 한다. 고온, 고습의 환경의 변화에 따른 유전율을 토대로 모의실험을 통해 안테나 커버의 특성을 평가하였으며, 최적의 소재인 테프론 코팅된 세라믹 복합체를 안테나 커버에 적용하여 우수한 물리적 및 전기적 특성을 실험적으로 증명하였다.
