Abstract
An apparatus and method relating to a rectangular waveguide cavity launch are disclosed that enable coupling an electromagnetic wave from the top surface of a waveguide distribution network formed into a conductive plate with the narrow wall of a rectangular waveguide facing the top of the conductive plate. A resonant cavity structure is formed into a conductive plate and coupled to a waveguide also formed into the plate, the resonant cavity structure having a cavity width wider than the narrow wall dimension of the waveguide. The resonant cavity structure includes a conductive block within it having a block width substantially equal to a difference between the cavity width of the resonant cavity structure and the narrow wall dimension. The cavity launch excites and rotates a dominant waveguide mode entering the structure such that the dominant waveguide mode enters the waveguide substantially parallel to the narrow wall dimension.
