Abstract

The FDTD(Finite-Difference Time-Domain) method is applied to analyze an unequal Wilkinson power divider. Unequal Wilkinson power divider has complex structures and the standard Yee Cell modeling method is not appropriate. In this paper, nonuniform gridding and subcell modeling are used to accurately analyze the characteristics of an unequal Wilkinson power divider. For comparison, the numerical results are presented with those from a commercial circuit simulator.

비둥분 Wilkinson 전력 분배기의 해석을 위해서 유한 차분 시간 영역 해석법올 적용하였다. 비등분 Wilkinson전력 분배기는 복잡한 구조로 이루어져 있어 기존의 Yee셀 모델링 방법을 사용하는 것은 적당하지 않다. 본 논문에서는, 비균등 직교 그리딩과 서브셀 모텔링 방법을 사용하여 비둥분 Wilkinson 전력 분배 기의 특성을 넓은 주파수 범위에서 정확하게 구하였다. 수치 해석 결과를 비교하기 위해서 회로 시뮬레이터 의 결과와 함께 제시 하였다.
