본 논문에서는 짧은 슬롯 2평면 커플러에 대한 모드 매칭(MM)/유한 요소법(FEM) 하이브리드 분석과 유전 알고리즘(GA) 기반의 광대역 설계 최적화 프로세스를 제시합니다. 분석 방법은 계산 시간을 줄이는 MM의 빠른 모달 분석과 임의 단면에 사용할 수 있는 FEM의 유연성을 결합합니다. 분석에서는 2.4차원 구조대칭을 이용하여 모델을 6.9/2 모델로 축소하였다. 계산된 결과는 시뮬레이션 결과와 잘 일치하며 계산 시간이 단축됩니다. GA 기반의 최적화를 통해 대역폭이 5.4면 하이브리드 커플러의 경우 7.5%에서 2%로, XNUMX면 크로스 커플러의 경우 XNUMX%에서 XNUMX%로 향상되었습니다. 측정된 결과는 광대역 설계를 확인시켜 줍니다.

Abstract: This paper presents the mode matching (MM)/finite element method (FEM) hybrid analysis for a short-slot 2-plane coupler, and an optimization process for a wideband design based on a genetic algorithm (GA). The method of the analysis combines a fast modal analysis of the MM which reduces the computation time, with the flexibility of an FEM which can be used with an arbitrary cross-section. In the analysis, the model is reduced into the one-eighth model by using the three-dimensional structural symmetry. The computed results agree well with those by the simulation and the computation time is reduced. The bandwidth is improved by the optimization based on the GA from 2.4% to 6.9% for the 2-plane hybrid coupler and from 5.4% to 7.5% for the 2-plane cross coupler. The measured results confirm the wideband design.
