基片集成波导功分器仿真设计

Simulation and Design of Substrate Integrated Waveguide Power Dividers

为了实现毫米波电路小型化设计,探讨了基片集成波导(SIW)功分器的工作原理,介绍了SIW功分器的设计规则和关键技术,使用HFSS仿真设计并实际制作了一个Ka波段SIW功分器,测试结果表明其在毫米波频段具有良好的性能,且结构简单,易于生产。

Substrate Integrated Waveguide（SIW） is a new type of guided wave structure which takes a lot of merits such as high-Q, low loss. And it can be easily integrated with microstrip or coplanar waveguide. It also can be easily designed and processed so that it can be widely implemented in microwave as well as millimeter wave integrated circuits. Based on the introduction of the theory and design rules of SIW power dividers, a Ka band SIW power divider is designed and simulated by HFSS, the test results show that the SIW power divider possesses good performance in millimeter wave band, and it＇s simple to be manufactured.
