초록

사각 마이크로스트립 패치 안테나의 입력 임피던스와 방사패턴에 대한 공기 갭과 이방성 기판의 영향을 적분 방정식 공식에 사용하여 연구하였다. 갈러킨 모멘트법을 사용하여 적분 방정식을 해석함으로서 입력 임피던스와 방사패턴을 얻을 수 있다. 기저함수의 선택은 패치 위의 실제 전류밀도와 가장 유사한 형태인 정현적 기저함수를 선택하였다. 전사모의 실험결과로부터 공기 갭의 두께, 기판의 이방성 비와 이방성 기판의 비유전율 변화에 따른 입력 임피던스와 방사패턴의 변화를 나타내었다.

Effects of Airgap and anisotropy substrate on input impedance and radiation pattern of rectangular microstrip patch antenna are studied in terms of an integral equation formulation. The input impedance and radiation pattern of microstrip patch antenna is investigated by using Galerkin's moment method in solving the integral equation. Sinusoidal functions are selected as basis functions, which resemble in the actual standing wave on the Patch. From the numerical results, the variation of input impedance and radiation patterns in the variation of air gap thickness, anisotropy ratio of substrate, and relative permittivity of anisotropy substrate are presented.
