摘　　要：使用多模谐振的加载支节设计了一种小型化双频滤波器。多模谐振加载支节由三条开路支节并联组成,通过调整这三根支节的长度,其前两个谐振模式可调整到一个频段内,而后两个谐振模式可以设计到另外的频段上,从而实现高隔离度的小型化双频滤波器。仿真与实测结果验证了上述设计思路。A miniaturized dual-band filter based on a stub-loaded multi-mode resonator （MMR） is design. The MMR is composed of three loaded open-ended stubs which are connected in parallel. By properly adjusting lengths of these stubs, the first two resonant modes of the MMR can be allocated within a same band, while the last two resonant modes can be allocated within another band; therefore a novel dual-frequency filter with compact-size and high isolation is obtained. The design concept mentioned above is verified by the simulation and measurement results.
