Microstrip Antenna for SAR Applications with Microwave Composite Laminates and Honeycomb Cores

복합재료 하니콤 샌드위치 판넬을 이용한 SAR 시스템용 마이크로스트립 안테나 개발

Microstrip antenna for SAR applications is designed with microwave composite laminates and Nomex honeycomb cores, which becomes an aircraft's structural panel. This study demonstrated fabrication, design procedures and structural and electrical performances of complex antenna system presented. For validating structural rigidity, 3-point bending test is performed, and simulation results for the complex antenna array are compared with measurements for its electrical performance. The results show that this antenna system can be applied in dual polarized synthetic aperture radar and has a good flexural stiffness with comparison of previous sandwich constructions.
