É proposto um método simples para melhorar as características fora de banda de um filtro planar de microondas. Esclarecemos a estreita relação entre 'conexão de derivação', 'pólo de atenuação' e 'respostas espúrias' no projeto de filtros, teórica e experimentalmente. Primeiramente, são examinadas as características básicas do ressonador dependendo do método de excitação. Mostramos que as características da saia podem ser melhoradas e respostas espúrias podem ser suprimidas usando a técnica de conexão de derivação. Em segundo lugar, são fornecidos exemplos de aplicação de filtros passa-banda (BPFs) com base no ressonador com nosso princípio. Confirma-se que o ressonador dependendo do método de excitação é útil para melhorar as características fora de banda do filtro de microondas planar.

Abstract: A simple method for improving out-of-band characteristics of a planar microwave filter is proposed. We clarify the close relationship among 'tap connection,' 'attenuation pole' and 'spurious responses' in filter design, theoretically and experimentally. Firstly, the basic characteristics of the resonator depending on the excitation method are examined. We show that skirt characteristics can be improved and spurious responses can be suppressed by using the tap connection technique. Secondly, the application examples of bandpass filters (BPFs) on the basis of the resonator with our principle are provided. It is confirmed that the resonator depending on the excitation method is useful for improving out-of-band characteristics of the planar microwave filter.
