| 摘 要： | 文章提出了一种基于分支线加载谐振器的三频带通滤波器的设计方法。通过理论分析和全波仿真发现,提出的分支线加载谐振器的奇偶模谐振频率均可以灵活的加以控制。基于这种新型的谐振器,设计了一个三频带通滤波器,该滤波器具有很小的插入损耗和很好的选择性。提出的设计与实验测试结果基本吻合。

| Abstract: | A tri-band bandpass filter using Stub-Loaded Resonators(SLRs) is presented.Characterized by both theoretical analysis and full-wave simulation,the proposed SLR is found to have the advantage that the even-mode resonant frequencies and the odd-mode resonant frequencies can both be flexibly controlled.Based on the proposed SLR,a tri-band filter is implemented with low insertion loss and high selectivity.The measured results validate the proposed design. |
