In this paper two novel frequency-dependent coupling structures (FVC) in rectangular waveguide are introduced. The main features of these FVCs are: 1) only a transmission zero is generated (no reflection zeros in the waveguide monomodal band). 2) Very high values for the equivalent slope parameter can be realized. 3) The structure is relatively compact. The use of the novel structures in FVC filters is illustrated by the design of two test filters.

Abstract
In this paper two novel frequency-dependent coupling structures (FVC) in rectangular waveguide are introduced. The main features of these FVCs are: 1) only a transmission zero is generated (no reflection zeros in the waveguide monomodal band). 2) Very high values for the equivalent slope parameter can be realized. 3) The structure is relatively compact. The use of the novel structures in FVC filters is illustrated by the design of two test filters.File in questo prodotto:
