RF module with integrated waveguide and attached antenna elements and method for fabrication

Abstract:

A radio frequency (RF) module may comprise: (a) a substrate including a plurality of integral waveguides formed therein, each of the plurality of waveguides orthogonally-oriented with respect to the one or more adjacent waveguides; and (b) a plurality of antenna radiator elements attached to the dielectric substrate and oriented such that a pair of antenna radiator elements is electrically coupled to one of the plurality of waveguides. Each of the integral waveguides is electrically coupled to electrical circuitry of the RF module.
