Abstract

This paper suggests a test and evaluation procedure of conformal load-bearing antenna structure(CLAS) for high speed military jet application. A log periodic patch type antenna was designed for multi-band communication and navigation antenna. Carbon/Glass fiber reinforced polymer was used as a structure supporting aerodynamic loads and honeycomb layer was used to improve antenna performance. Multi-layers were stacked and cured in a hot temperature oven. Gain, VSWR and polarization pattern of CLAS were measured using anechoic chamber within 0.15~2.0 GHz frequency range. Tension, shear, fatigue and impact load test were performed to evaluate structural strength of CLAS. Antenna performance test after every structural strength test was conducted to check the effect of structural test to antenna performance. After the application of new test and evaluation procedure to validate a new CLAS, a design improvement was found.

본 논문에서는 전투기 주구조물에 적용할 수 있는 안테나 내장 스킨구조(CLAS)의 새로운 시험평가 절차를 제시하였다. 대수 주기 패치형 안테나를 통신항법용 다중대역 안테나로 설계하였다. 탄소/유리 섬유 강화 적층 복합재(CFRP/GFRP)를 공력하중을 지지하기 위한 구조로 사용하고 안테나 성능 향상을 위해 하니컴 층을 적층하였다. 여러 재질로 구성된 다층구조의 안테나 내장 스킨구조를 고온의 오븐에서 경화하였다. 내장된 안테나의 이득, 전압 정재파비, 방사패턴을 0.15GHz~2GHz 주파수 범위에서 무반향 챔버시설을 이용하여 측정하였다. 안테나 내장 스킨구조의 구조강도를 평가하기 위하여 인장, 전단, 피로, 충격 하중을 부가하는 구조시험을 수행하였다. 각각의 구조시험 후에 안테나 성능시험을 수행하여 초기 값과 비교하므로써 구조시험이 안테나에 미치는 영향을 확인하였다. 새로 개발한 안테나 내장 스킨구조 시험평가 절차를 통신항법용 CLAS에 적용하여 설계개선이 필요한 점을 발견하였다.
