Computer-Aided Design of Millimeter-Wave E-Plane Filters

A computer-aided design (CAD) algorithm has been developed for a class of E-plane bandpass filters. The analysis portion of the algorithm is based on the residue-calculus technique and a generalized scattering parameter method. It is mathematically exact and numerically very efficient. Filters designed with this method have been fabricated and tested in Ku-band. Good agreement with design has been obtained.
