摘要
利用模匹配方法和网络理论分析计算了一种卫星天线系统中常用的波导分支线定向耦合器,计算结果与实验结果非常吻合。该方法为波导分支线定向耦合器提供一种有力的设计手段。它可直接用于设计Ku 波段通信卫星天线的波束形成网络,也可以用来设计各种耦合度的波导分支线定向耦合器。
An analysis of waveguide branch-line directional coupler,whieh is used on spacecraft,is given in this paper using network theoryand mode match method.By taking into account of the high order mode coupling,the calculationresult is very coincident with the test data of an experimental sample.Therefor the method given here provides a powerful tool for the design ofwaveguide branch-line directional coupler,and can be directly used for de-velopment of the BFN of Ku band shaped beam antenna system of communi-cation satellite and for the areas where the waveguide coupler with dif-ferent couple coefficient such as various waveguide beamforming networkis used。
