本文描述了一个多层介质双工器的设计,并给出计算机模拟结果的曲线。本双工器可以把来自一路频率比为1/2(或2/3)的两个均为圆极化的信号分开,并有极好的频率特性和传输特性,反之也可把来自两路的频率比为1/2(或2/3)的圆极化信号合为一路。这是在微波和毫米波通讯中,解决双频圆极化共用天线问题的一个新方案。
This article describes the design of a multilayer dielectric duplexer and gives the curve of computer simulation results. The duplexer can be from all the way to the frequency ratio of 1/2 (or 2/3) of the two are circularly polarized signal separation, and have excellent frequency characteristics and transmission characteristics, on the contrary can also be from two Frequency ratio of 1/2 (or 2/3) of the circular polarization signal together. This is a new solution to the problem of dual frequency circular polarization shared antenna in microwave and millimeter wave communication.
