摘要

本文分析了一种新型实用的微波滤波器结构:在矩形波导中插入圆柱形介质谐振器。文中将谐振器作为波导中的不均匀性

用模匹配法准确分析了其散射特性。理论结果不仅能计算谐振频率

而且还给出散射矩阵等网络参数。本文的理论分析与实验检测量结果吻合很好。通过理论与实验研究

本文对衬底的作用作出了新的解释。

Abstract

A typical structure of microwave filter

i.e. rectangular waveguide inserted with cylindrical dielectric resonators has been developed. By applying mode-matching technique

the scattering characteristic of the resonator is accurately analysed. As a result

the network parameters and the resonant frequency are obtained. The theoretical results are in goo agreement with those of experiments. The significant effect of the substrate on choosing the resonant modes is also revealed in theory and experiments.
