Este artigo apresenta a análise híbrida de correspondência de modo (MM)/método de elementos finitos (FEM) para um acoplador de 2 planos de slot curto e um processo de otimização para um projeto de banda larga baseado em um algoritmo genético (GA). O método de análise combina uma análise modal rápida do MM que reduz o tempo de cálculo, com a flexibilidade de um FEM que pode ser usado com uma seção transversal arbitrária. Na análise, o modelo é reduzido ao modelo um oitavo usando a simetria estrutural tridimensional. Os resultados calculados concordam bem com os da simulação e o tempo de cálculo é reduzido. A largura de banda é melhorada pela otimização baseada no GA de 2.4% para 6.9% para o acoplador híbrido de 2 planos e de 5.4% para 7.5% para o acoplador cruzado de 2 planos. Os resultados medidos confirmam o design da banda larga.

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.
