In this paper, we describe a new family of dual-mode filters that is based
on the use of simple inductive discontinuities in a rectangular waveguide e
nvironment. The proposed filter structure can be analyzed and optimized ver
y efficiently using multimode equivalent network representations, thus lead
ing to a simple and rapid development procedure. In addition to theory, the
measured performance of a number of filter structures is also presented, t
hereby fully validating the proposed filter concept.
