A novel bandpass filter based on Half-Mode substrate integrated waveguide (HMSIW)

A novel branched-shaped bandpass filter structure of Half-Mode substrate integrated waveguide is presented. By etching branched-shaped resonators with different patch size, wide pass-band is obtained, the filter was fabricated with a single layer standard printed circuit board process. The measured...

Description
Summary:A novel branched-shaped bandpass filter structure of Half-Mode substrate integrated waveguide is presented. By etching branched-shaped resonators with different patch size, wide pass-band is obtained, the filter was fabricated with a single layer standard printed circuit board process. The measured results are in good agreement with the simulated results, that indicates the correctness and effectiveness of the design. The bandpass filter structure has the advantage of low insertion loss, compacted and good selectivity.
