摘要
本文设计了一种基于基片集成波导(SIW)用于Ku波段的滤波器。这种微波滤波器有着高性能,低成本等优点,电路性能得到大幅提高。滤波器通带频率为12.5GHz-13.0GHz,带内插入损耗约为2db,带内回波损耗大于20db。结果表明,该滤波器在Ku波段能很好的实现滤波功能。
This paper proposed a new kind of filter based on substrate integrated waveguide which is used in K band. This kind of microwave filter has the advantages of high performance, low cost and circuit performance has been greatly improved. Filter worked at 12.5GHz‐13.0GHz, the insertion loss is about 2d B, and the return loss is greater than 20 d B.
