Abstract

Though microstrip antenna has several advantages, it makes engineers struggle against the difficulties of narrow bandwidth and scan-blindness with probe-feeding and array configuration. To overcome these disadvantages, stacked patch and cavity-backed structure had been proposed. But this structure can not be analyzed easily because we have no concrete means to analyze it. So the algorithm to analyze the structure should be established to make it useful. This paper explained the algorithm of moment method to analyze the structure and verified it by comparing the calculated and measured results.

마이크로스트럼 안테나는 여러 가지 장점에도 불구하고 협대역이라는 단점과 배열 안테나 구현 시에 나타나 는 표면 전파에 의한 음영각의 문제점에 의해 구현에 상당한 어려움을 가지게 된다. 이러한 문제를 해결할 수 있는 구조로 적층 구조와 cavity-backed 구조를 들 수 있는데, 반면 이러한 구조는 해석 및 설계가 쉽지 않은 상황이다 본 논문에서는 모우멘트볍올 사용하여 적층형 cavity-backed 원행 마이크로스트립 안테나를 해석하고 이를 이용하여 X-band 대역에서 안테나를 설계. 구현하여 봄으로써 적절한 해석이 이루어졌음을 검증하였다.
