Abstract

In this paper, the electromagnetic wave transmission through a ridge-loaded small circular aperture is considered. The transmission problem when a plane wave is normally incident on the aperture in an infinite conducting plane is solved by a method of moments(MoM). From the results for the transmitted power and the patterns of radiation from the aperture, the transmission characteristics of a small sub-wavelength circular aperture, a ridge-loaded circular aperture, and a half wavelength slot are compared. In addition, the theoretical study is verified through the experiments for the apertures fabricated on an Flexible Printed Circuit Board(FPCB), which shows fairly good agreements with the simulated results.

본 논문에서는 파장에 비해 작은 원형 개구를 통한 전자파 투과를 고려하였다. 무한 도체판의 개구에 대해 수직으로 평면파가 입사될 때 투과 문제를 모멘트 방법으로 풀었다. 투과된 전력과 개구로부터의 복사 패턴에 대한 결과들로부터 파장에 비해 작은 원형 개구, 리지가 장하된 원형 개구 및 반 파장 슬롯의 투과 특성을 비교하였다. 그리고 이론 연구의 타당성을 검증하기 위해 FPCB상에 제작된 개구의 투과 특성을 실험하였으며, 그 결과 시뮬레이션 결과들과 잘 일치함을 관찰하였다.
