Abstract

A new type of filter using degenerate mode is studied by applying the pertur bation theory. The eigenvalues of degenerate mode of TE010 and TE100 in square planar circuit can be lifted by the small perturbation on its boundary and then the perturbed square planar circuit presents a flat pass-band response with very low insertion loss in the pass-band. Both theoritical and experimental results of this filter are given.
