摘　　要：提出了利用介质材料进行微扰实现多模谐振的微带谐振器设计方案。首先分析了材料微扰多模谐振器的谐振机理,然后在谐振器两端介质材料不变情况下,通过改变谐振器中间部分的介质材料,分别设计了两端开路和两端短路的半波长微带多模谐振器。仿真结果表明,上述不同设计得到的微带谐振器均可实现简并模分裂,具有多模谐振的特点。Here is proposed a design scheme of the microstrip multimode resonators using dielectric materials for perturbation to achieve multimode resonance. Firstly, we analyzed the multimode resonance mechanism based on the material perturbation. Under the condition of fixed dielectric materials at both ends of the resonator, both the half-wavelength open- and short-ended microstrip multimode resonators were then designed by simply changing the dielectric material in the middle part of the resonator. The simulation results indicate that the obtained microstrip resonators could realize splitting of degenerate mode and thereby achieve multimode resonance.
