  • the two output side waveguides are replaced by a single waveguide 40 connecting the two output ports 11, 21. If the input waveguide 30 is disposed at the lower level and the output waveguide 40 is located at the upper stage, the coupling in the plane E is effected by arranging a slot 35 at the end of the input waveguide 30, in the upper wall, and a corresponding slot in the center of the bottom wall of the output waveguide 40 connecting the two output ports.
