Abstract:
A bandpass filter based on novel spoof surface plasmon polaritons (SSPPs) and substrate integrated waveguide (SIW) is reported. The filter consists of a conventional SIW structure and a ring slot array etched on the top metal layer of the SIW to excite SSPP modes. The passband of the filter can be adjusted by changing the dispersion characteristics, which can be realized by tuning the specific parameters of the unit cell. The simulation results indicated that the proposed structure has great filter characteristics within a passband from 13 to 24.1 GHz with minimum insertion loss of 0.42 dB at 17.8 GHz. © 2021 IEEE.
