BJ-320波导对称五端口测量网络设计

Designing a Symmetrical Five-Port BJ-320 Waveguide Junction

介绍了工作于26．4～40GHz频带的对称五端口波导网络的设计方法。为了使五端口波导网络能较好地工作于六端口反射计中，要求各端口反射系数的绝对值小于0．2（｜S11｜≤0．2）。这里结合了频移法、渐变线分割研究法和数值解法等理论对五端口波导测量网络进行设计。

The study has shown to design a symmetrical five-port wave which is from 26.4 GHz to 40 GHz. For the five-port waveguide guide junction working in the bandwidth, tion properly to be used in a six-port reflectometer, needing the reilection coefficient looking into anyone port is less than 0.2（ ｜S11｜〈0.2）in the bandwidth. The study has applied the frequency bandwidth move, the cutting taper apart method and the mathcmatie analysis to design a symmetrical five-port waveguide junction.
