Abstract
본 연구에서는 기계적 전기적 기능을 모두 만족하는 다중대역 스킨구조물에서의 복사 소자를 2중 사출으로 제작하였다. 추후 외부 스킨 구조 변형에 따른 복사 소자의 안정성을 검증하기 위하여 충격 및 좌굴에 대한 시험과 축 하중과 전단 하중에 대한 강도 해석을 실시하였다. 그리고 다중 대역 안테나 스킨 구조의 복사 소자에 대한 실험적 방법과 해석적 방법을 통한 강도 분석 결과, 구조의 허용 하중을 예측하고 충격과 좌굴에 대한 안정성을 평가할 수 있었다. This study manufactured the radiating element of multi-band antenna skin structure which satisfy electrical and mechanical performance and is made by double injection molding process. Structural test including impact and buckling test is carried out and stress analysis is simulated to evaluate safety of radiating element for the axial and shear loads, when changing of the skin structure is occurred by the external force. To predict allowable load of structure and evaluate safety on impact and buckling, experimental and analytic method is used in strength analysis of structure.
