  • W-band E-plane waveguide bandpass filter
    Patent number: 11682817
    Abstract: A W-band E-plane waveguide bandpass filter includes a rectangular waveguide configured to feed a W-band signal, and a dielectric substrate. The dielectric substrate is inserted into the center of the waveguide. The dielectric substrate is provided with a spoof surface plasmon polariton (SSPP) array configured to transmit a TM-mode surface wave to achieve the bandpass filtering response.
    Type: Grant
