Abstract

This paper presents a novel realization of fully canonical and pseudo-elliptic wideband rectangular waveguide filters. Authors proposed a novel coupling structure in [1] that has the capability to realize a positive coupling, a negative coupling, or a TEM resonator by adjusting its length. A number of filters were realized using the novel coupling structure. In this paper, design of one fully canonical filter and four pseudoelliptic filters at the center frequency of 10 GHz is presented utilizing the novel coupling structure. One of the filter has an equiripple bandwidth of 1.5 GHz. Rigorous full-wave EM simulations have been performed, results demonstrate that the realization of such filters is feasible and desired number of transmission zeros can be generated at the prescribed positions.
