波导型定向滤波器的研究

Research on Waveguide Directional Filter

定向滤波器是一个完全匹配的四端口器件,它有着类似滤波器的频率特性。波导型定向滤波器利用圆极化波导来实现信号的定向分配,本文介绍了它的原理及设计方法,给出了仿真实例。

A directional filter is a completely matched four-port device which exhibits a filter-like frequency characteristic.Circularly polarized waveguides can be used by a waveguide directional filter to real- ize the directional properties.This paper introduces the principle and design with a simulation example.
