SIW/HMSIW Bandpass Filters for Ka Frequency Band Serving Wireless Applications

This paper describes a novel Substrate Integrated Waveguide (SIW) bandpass filter using Chebyshev approximation and Half Mode (HMSIW) modeling technique. The developed 3 rd order structure uses an inductive iris post station in way it resonates Ka frequency band serving wireless applications. presents details steps of the design formed by specific analytical equations to extract its different synthesizable parameters including coupling matrix, quality factor initial geometric dimensions. ideal response is determined from equivalent circuit that localized elements AWR Microwave Software. High Frequency Structure Simulator (HFSS) then employed model proposed optimize until meeting target specifications initially fixed provide high for design. Finally, obtained results display good performance demonstrate usefulness technology allows low volume.
