The present disclosure relates to waveguide band-stop filter arrangement adapted to be connected to a waveguide transmission line at a filter interface, where the waveguide transmission line is adapted for a main propagation extension. The band-stop filter arrangement comprises a first pair of cavities, where each cavity in the first pair, each first pair cavity, comprises a corresponding inductive first pair aperture arrangement that is adapted to connect the corresponding first pair cavity to the waveguide transmission line. The first pair cavities are positioned adjacent each other along a stacking extension perpendicular to the main propagation extension such that they share a first common wall and are adapted to be positioned adjacent the waveguide transmission line. The first pair of cavities comprises a first capacitive aperture arrangement in the first common wall, mutually connecting the first pair cavities.
