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 (<1 dB) and high out-of-band rejection (> 40 dB).
