波导E面金属片滤波器的优化设计
AN OPTIMIZATION DESIGN OF WAVEGUIDE E-PLANE METAL INSERT FILTERS
-
摘要: 本文采用模式展开方法,导出了波导E面金属片滤波器的散射参量,进而编写了滤波器优化设计程序,设计、制造和测试了一个长三厘米滤波器,实验结果和理论结果符合得很好。本文方法考虑了高次模式通过谐振腔发生的耦合,设计的滤波器特性比较理想,在频率的低端和高端阻带衰减都较大,所以比采用变分原理导出等效网络参数然后进行综合设计的方法优越。

Abstract: An optimization design theory and algorithm have been developed for waveguide E-plane metal insert filters. The immediate higher order mode coupling in resonator between the discontinuities, which reduces the stop band attenuation for higher frequencies is taken into account. An optimized design filter has been fabricated and tested in low X-band. Good agreement with design has been obtained. -
