8mm波导魔T的仿真分析

介绍了一种8 mm波导魔T的设计,采用仅在魔T接头处加入匹配元件,设计出了一种结构简单的魔T结构形式,并使用三维仿真软件对其进行仿真计算。仿真结果表明:在32.5~37.5 GHz范围内实现了功率等分,端口间的隔离度优于-30 dB,回波损耗小于-20 dB,等分臂功率差值小于0.1 dB,工作带宽大于14%。

Simulation and Analysis of 8 mm Waveguide Magic Tee

The design of a kind of 8 mm waveguide magic T has been introduced.Only a matching element is placed in the junction,simplified the structure of the magic tee,simulated and calculated the waveguide magic T by 3D electromagnetic simulation software.Simulation results indicate that equal power division has been realized from 32.5 GHz to 37.5 GHz.The isolation is better than-30 dB.The return loss is less than-20 dB and the power different between two equal arms are less than 0.1 dB.Good performance has been obtained about the relative bandwidth of more than 14 percent.
