摘要
在L、S等较低的微波频段,带状线交指滤波器是常用的滤波器之一。文献上一般只给出比较详细的矩形杆间距和带状线宽度的设计公式,对于谐振杆长度l或者端间隙Sa的确定,以及终端杆边距S0的确定,仍然要通过实验方法不断修改多次才能完成。提出了十分简单准确有效的电容间隙Sa的设计方法,即Sa=b/4,解决了一直困扰工程师的一个难题。
Comb stripline filters are common filters in lower microwave frequency band,such as L-band and S-band.The resonance rectangular bar length l,the edge distance S0,especially the capacitive gap Sa are determined difficultly in the practice.Generally,they are determined by many experiments.So,an effective method of capacitive gap （Sa=b/4） is presented,which has been used in many engineering projects.
