ABSTRACT:
A multiple channel microwave rotary joint is disclosed which is a toroidal cavity having first and second halves each with a bearing surface for rotation about the axis of the toroid. A plurality of input ports are mounted about the external cylindrical surface of the first half for generating a plurality of modes within the toroidal cavity. A first hybrid network is coupled to the inut ports for providing the proper phase input signals for generating the various modes. A second hybrid network is connected to a plurality of output probes mounted to the second half of the toroidal cavity. The rotary joint has a passageway which is axially aligned for allowing a plurality of multichannel rotary joints to be "stacked" and the interconnecting microwave cables or waveguides to pass through the passageways.
