Abstract

The mutual coupling of a pair of microstrip patch antennas on a finite grounded dielectric substrate is influenced by the diffracted field of surface waves from the edges of a substrate. The effective dielectric constant of a grounded dielectric substrate determines the distance between the antenna center and the edge of a substrate to obtain the minimum mutual coupling between a pair of microstrip patch antennas. The optimum substrate size with the minimum mutual coupling is easily calculated using the image method. The optimum substrate sizes using the linage method are in good agreement with the results obtained by the full wave simulation.

기판 크기가 유한하면 두 패치안테나간의 상호결합은 기판 가장자리에서 회절되어 들어오는 표면파에 의해 영향을 받는다. 상호결합이 최소가 되는 패치안테나 중심과 기판 가장자리까지의 거리는 접지된 기판의 유효 유전상수에 의해 결정됨을 알 수 있었다. 상호결합이 최소화되는 기판 크기는 이미지 방법을 사용하여 쉽게 계산 할 수 있다. 이미지 방법으로 계산한 최적화된 기판 크기와 전산모의 결과로 얻어진 최적화된 기판 크기가 잘 일치하였다.
