Abstract:
A generally fan shaped electrically conducting base member defining a waveguide cavity with a waveguide input/output in communication with the cavity at the apex thereof and a plurality of output/input waveguides in communication with the cavity equal angularly spaced along the arc of the base member. The inputs and outputs are formed in the plane of the cavity so that losses are substantially reduced and all of the output/input waveguides are equally spaced along radii of the base member and are of equal length so that signals at the outlets thereof are of equal amplitude and phase without requiring phase shifters and the like.
