Abstract

A modal analysis for the directional coupler is presented in this paper. The analysis is based on the mode-matching technique. The theory is verified by Ansoft HFSS software at a directional coupler with standard X-band (WR 90) rectangular waveguide ports. Element values of equivalent circuit model are computed by using the S-parameters obtained from the presented method in this paper. In addition this paper has corrected two formulations used in two previous works which have been published.

定向耦合器及其等效电路的模态分析

本文对定向耦合器进行了模态分析。该分析基于模式匹配技术。该理论在具有标准X波段（WR90）矩形波导端口的定向耦合器上通过Ansoft HFSS软件进行了验证。利用本文提出的方法得到的S参数，计算了等效电路模型的单元值。此外，本文还修正了前两部已发表的著作中使用的两种公式。
