Abstract
The present disclosure relates to a tunable waveguide filter input/output coupling arrangement comprising a waveguide part, a coupling iris part and a tunable filter part. The waveguide part runs along a longitudinal extension and has a waveguide width extending perpendicular to the longitudinal extension, and is electrically connected to the tunable filter part by means of the coupling iris part which comprises an opening between the waveguide part and the tunable filter part. The opening is positioned at a certain position along the longitudinal extension. The waveguide part comprises a stub part that has a certain stub length along the longitudinal extension, between an electrical short-circuit end plate and an edge of the opening that is closest to the end plate, where the stub part also has a stub width extending perpendicular to the longitudinal extension.
