Design of Parallel-Coupled Filter Based on Printed-Ridge Gap Waveguide

This paper proposes a fourth-order Chebyshev-type parallel-coupled filter in the printed ridge gap waveguide technology. The filter is designed to operate at the center of frequency f۰ = ۱۴.۸۵ GHz with ۶.۳۳% fractional bandwidth. A method using Fullwave solvers such as ANSYS HFSS is utilized for extracting the characteristic impedances to design the resonators and the filter. Finally, the filter is realized using the graph providing the even- and odd-modes characteristic impedance Zceven and Zcodd.
