Ridged waveguide arrangement containing a first ridge waveguide overlapping a second waveguide to produce a capacitive coupling there between
A waveguide arrangement contains a first ridged waveguide and a second waveguide. The first ridged waveguide contains a first casing with a first cavity and a first ridge extending in the first cavity in the longitudinal direction. The first ridge is conductively connected to a wall of the first casing. The second waveguide contains a second casing with a second cavity. The first ridged waveguide overlaps the second waveguide in the longitudinal direction of the waveguide arrangement in a connecting section to produce a capacitive coupling between the first ridge and the second waveguide.
