| 摘 要： | 提出一种通过提升设计频率来解决平行耦合微带带通滤波器中边缘场效应导致的中心频率偏移的方法。同时分析了导致这种偏移的原因,并阐述了该方法的理论基础。给出的实例证明,在使用微波软件设计平行耦合微带线带通滤波器时,这种方法是简洁且可行的。

| Abstract: | In this paper,an optimized design method is presented to deal with the edge field effect problem in the par- allel-coupled microstrip bandpass filters.The analysis on the relationship of the center frequency deviation and the microstrip open-end effect is given.Based on the theoretical analysis,a design example of 10GHz bandpass filter is presented,which has proved the availability of this method. |
