ABSTRACT:
The present invention is a compact, multiplanar magic-T junction that generally consists of four planar waveguides and/or planar transmission lines, with at least one planar waveguide or planar transmission line residing in a different circuit layer from the other planar waveguides and/or transmission lines. Each planar waveguide and planar transmission line in the multiplanar magic-T junction is electromagnetically connected to an input/output feeding port with which it communicates. The ground planes common to the planar transmission lines and/or planar waveguides in the magic-T junction contain a coupling aperture. The planar waveguides and planar transmission lines which are on different sides of the common ground planes of the magic-T junction communicate electromagnetically through this coupling aperture.
