中文摘要：
介绍了一种新型的Ka波段微带带通滤波器。对这种滤波器进行了分析,推导了滤波器产生慢波效应的机理。该滤波器通过加载电容而出现慢波效应,使得在不改变电路性能的情况下,减小了电路尺寸。同时由于电路中加载电容形成的慢波效应而出现了带阻效应,因此对谐波有很好的抑制作用。利用软件HFSS仿真分析并设计了这种新型的加载电容型Ka波段微带带通滤波器。
英文摘要：
A new Ka-band microstrip band-pass filter is introduced in this paper.The reasons of how the slow-wave effect is produced are also analyzed and deduced.The filter produces slow-wave effect through loading capacitance.The size of this filter is greatly reduced without changing the performance of the circuit.At the same time,the band-stop effect occurs in the filter owing to the slow-wave effect.Therefore it has good suppression for harmonic wave in the filter.This kind of new microstrip band-pass filter with loading capacitances is analyzed and designed by HFSS software.
