摘要
本文运用等效原理和并矢格林函数,采用矩量法分析了两矩形波导公共宽壁上多个位置处任意尺寸矩形槽的耦合特性,给出了波导定向耦合的分析和设计过程。该方法考虑了有限壁厚和高次模间的相互耦合等诸多因素。应用分析结果,设计和试制了工作于Ka波段和W波段的两个定向耦合器,实验结果和设计指标吻合较好。
In this paper, the equivalent theorem, the dyadic Green's function and the method of moments are employed to analyse the coupling characteristics of two rectangular guides with multirectangular slots of arbitrary dimension located in the common broad-wall. The procedure for analysing and designing waveguide directional couplers are also given. Some factors, such as the effect of finite wall thickness and the higher-order mode coupling within the slots, are considered in the approach. The directional couplers for Kaband and W-band were designed and tested. The experimental results agree well with the theoretical predictions.
