Abstract

An apparatus includes a printed circuit board having a first surface and a second surface opposite the first surface. The apparatus includes a surface launcher of a dielectric resonator antenna (DRA). The surface launcher is coupled to the first surface of the printed circuit board. A metal structure is coupled to the first surface and configured to direct a portion of a wave of the DRA through the second surface.
