Abstract

Microstrip open-end and linear resonator are analyzed by method of moment (MoM) taking the entire-domain current distribution, found in literature, along the transverse direction of microstrip line. A transverse correlation function which incorporates permittivity, thickness and width of the line is derived. Numerical examples are investigated and compared with the available other data and methods in order to give the validity of the proposed method. It is found that the proposed method can generate more accurate results than the conventional methods.

본 논문에서는 마이크로스트립 개방선로와 선형공진기에 대해서 라인의 측방향 전역함수를 이용하여 모멘트법으로 해석하였다. 마이크로스트립 라인의 기판의 유전율 두께와 라인을 폭을 포함하는 측방향의 상관함수를 유도하였다. 제안된 방법을 검증하기 위하여 몇가지의 수치해석 예제에 대하여 제안 방법과 다른 방법에 대하여 해석하여 그 결과를 비교하였다 이 방식이 기존의 방법에 대해서 보다 더 정확한 결과를 얻을 수 있음이 관측되었다.
