A system includes an electronic device coupled to a mating end of a dielectric wave guide (DWG). The electronic device has a multilayer substrate that has an interface surface configured for interfacing to the mating end of the DWG. A conductive layer is etched to form a dipole antenna disposed adjacent the interface surface. A reflector structure is formed in the substrate adjacent the dipole antenna opposite from the interface surface. A set of director elements is embedded in the mating end of the DWG. Specific spacing is maintained between the dipole antenna and the set of director elements.
