초록

개구결합으로 급전되는 마이크로스트립 안테나 구조에 대해, 접지면과 패치사이의 간격에 따라 ‘cavity'형과 ’parasitic'형의 두 가지 결합 메커니즘으로 나눌 수 있음을 이론적, 실험적으로 제시하였으며, 보다 단순한 급진구조로서 gap-결합 급전 마이크로스트립 안테나구조에서도 유사한 현상이 나타남을 확인하였다. 이러한 두 가지 결합메커니즘의 특징적 차이에 대하여 논의하였다.

This article describes an observation that the aperture coupling mechanisms in the aperture coupled microstrip antenna can be divided into two categories, cavity and parasitic types, depending on the separation between the microstrip patch and the ground plane. The similar phenomenon was observed in the relatively simple gap coupled microstrip antenna. The specific characteristics between two coupling mechanisms is discussed.
