| 摘 要： | 本文采用直线法对悬置微带交指带违滤波器（ＳＭＩＢＰＦ）做准静态分析，得出了电路和几何尺寸与静态多数之间的关泰然后结合Ｐｏｗｅｌｌ优化，编制出设计ＳＭＩＢＰＦ的通用程序，并制作了一个Ｓ波段窄带带通法波器，获得了满意的测试结果。可作为小型化通信设备中的收、发双工滤波器。

| Abstract: | The quasi-TEM mode analysis of suspended microstrip interdigidal band-pass filters(SMIBPF)is analyzed by using method of lines. The relation between the static characterizations andthe suspended microstrip geometry is obtained.Using Powell optimization technique,the microwaveCAD programs for SMIBPF are developed.A S-band filter is fabricated successfully,the experimentaland computed results agree well.This filter can be used as a duplex filter in the miniature communtca-tion system. |
