ABSTRACT:
An assembly of waveguides and coupling apertures located within walls separating the waveguides is formed within a planar configuration. The coupling apertures are arranged either singly or in pairs, with one coupling aperture behind the other coupling aperture, to provide for a division of power between waveguides and to provide for a crossing over of power from one waveguide to another waveguide. The waveguide assembly is reciprocal in operation so that the single coupling apertures may be employed for a distribution as well as for a combination of electromagnetic waves. Phase shifters may also be included to provide a desired phase relationship among waves outputted by various ones of the waveguides. The waveguides, the walls separating the waveguides, the coupling apertures and the phase shifters may all be fabricated in a parallel array within a common metallic plate by automated milling machines for facile, accurate, and reproducible manufacture of the wavguide assembly. The waveguide assembly including the matrix of passages for electromagnetic waves is readily structured to serve as a Butler matrix.
