Abstract
A rotary coupler for coupling a microwave signal to a rotating antenna is disclosed. The preferred embodiment comprises a section of waveguides formed into a circle and split into two pieces along the long wall of the waveguide. The two sections of waveguide are positioned to rotate with respect to each other with energy coupled into one portion of the waveguide along its narrow wall and coupled out of the second portion along its narrow wall. An isolation element is utilized at both the input and output ports to assure directional coupling into the split wall waveguide. More than one of the coupling devices can be monitored around a ship's mast, for example, to couple a plurality of microwave systems to a single multiple bandwidth rotating antenna.
