提出了一种基于混合欺骗表面等离子激元（SSPP）和半模基片集成波导（HMSIW）的带通滤波器。该滤波器由传统的HMSIW结构和蚀刻在HMSIW顶部金属层上的E型缝隙阵列组成，以支持SSPP模式。滤波器的通带可以通过改变色散特性来调节，而色散特性的调节可以通过调节单元格的参数来实现。仿真结果表明，该结构在3.05 ~ 3.65GHz的通带内具有良好的滤波特性，回波损耗大于15 dB，插入损耗小于40 dB。
A bandpass filter based on hybrid spoof surface plasmon polaritons (SSPPs) and half-mode substrate integrated waveguide (HMSIW) is proposed. The filter consists of a traditional HMSIW structure and an E-type slot array etched on the top metal layer of the HMSIW to support SSPP modes. The passband of the filter can be adjusted by changing the dispersion characteristics, which can be realized by tuning the parameters of the unit cell. The simulation results show that the proposed structure has great filter characteristics within a passband from 3.05 to 3.65GHz with high return loss (> 15 dB), low insertion loss ( 40 dB).
