摘　　要：介绍了一种在超宽带滤波器中增加阻带来实现双频带通滤波器的方法,提出用加载三个开路支节的多模谐振器来实现适用于WLAN网两个通带的双频宽带带通滤波器,并通过对支节的弯曲进一步实现了小型化。仿真结果表明本设计的双宽带带通滤波器实现了良好的频率选择性和带内特性。In this paper,a way to realize dual-wideband bandpass filter by inserting a stopband within a UWB filter is proposed.A novel dual-wideband bandpass filter based on symmetrical multi-mode resonator with three open stubs is proposed for WLAN bands.In addition,the folded open stub is used to further reduce the size of the dual-wideband bandpass filter.The simulation results show that the high selectivity and good in-band performance can be achieved in the dual-wideband bandpass filter.
