摘要 为了得到两个通带中心频率及带宽均可独立调节的小型双频滤波器,提出了一种基于组合谐振器的双频滤波器设计方法.该滤波器由两组不同的l/4微带谐振器组合而成,并由它们谐振产生两个不同的通带.通过调节每组谐振器之间的耦合缝隙,可以独立地控制每个通带的带宽.最后设计加工了一个工作在2.4和5.2 GHz的双频滤波器并进行了实验,实测结果和仿真结果基本吻合,从而验证了这种设计方法的有效性. Proposed in this paper is a compact dual-band filter based on the combined resonators,in which the two central passband frequencies and bandwidths are all tunable.The filter is composed of two sets of l/4 microstrip resonators that produce two different passbands.By adjusting the coupled spacing between the adjacent resonators in each set,the bandwidth for either the lower or the upper passband can be independently adjusted.Moreover,a dual-band filter operating at 2.4 and 5.2GHz is designed and manufactured.The measurement results basically accord with the simulation ones,which validates the effectiveness of the proposed design.
