摘要

In this article, a novel design way of wideband bandpass filter (BPF) is proposed. A hybrid sharing waveguide based on spoof surface plasmon (SSP) and half-mode substrate integrated waveguide (HMSIW) is developed. With low-pass feature of SSP and high-pass feature of HMSIW, the proposed waveguide is a BPF naturally and the filter bandwidth can be controlled by adjusting parameters easily. A filter sample is fabricated for verification and the measured 3-dB bandwidth is 46%. The proposed new concept of filter design is attractive and can be used to develop different wideband BPFs.
