Abstract

A three-dimensional finite difference time domain (3-D FDTD) algorithm of calculation for the characteristics of coaxial-to-cavity filter including a discended probe and a tuning post is presented. In the arrangement the inner coaxial conductor protrudes into the cavity and operates as a probe radiator. And the height of the rectangular tuning post determines the resonant frequency. The validation of this method is confirmed by comparing the calculated values with experimental results for the designed filter.

본 논문에서는 종단판 프로브와 동조 포스트가 포함된 동축선 대 캐비티 필터의 특성을 3차원의 시간영역 유한차분(3-D FDTD) 방법에 의해서 계산하였다. 이 필터는 캐비티 안으로 삽입된 동축선의 내부도체가 복사체 역학을 하며, 사각혀 ㅇ동조 포스트의 높이에 의해서 공진주파수를 결정하게 되는 구조이다. 이러한 필터 특성의 계산값과 실제 제작된 필터의 측정값을 비교하여 이 해석 방법의 유용성을 확인하였다.
