Patent ID: 8878728

Claim:
A parasitic antenna array, comprising: a substrate, the substrate including a first surface and a second surface disposed generally opposite the first surface; a central monopole element configured to radiate electromagnetic energy, the central monopole element being disposed within a central monopole element through-hole of the substrate and extending from the first surface of the substrate to the second surface of the substrate, the central monopole element formed by plating a portion of the substrate encompassing the central monopole element through-hole with a metallic material; a plurality of parasitic elements at least substantially surrounding the central monopole element, each of the plurality of parasitic elements being disposed within a parasitic element through-hole of the substrate and extending from the first surface of the substrate to the second surface of the substrate, each of the plurality of parasitic elements formed by plating a portion of the substrate encompassing a parasitic element through-hole with a metallic material; a ground plane, the ground plane disposed on the second surface of the substrate; and a plurality of load circuits, each load circuit being connected to one or more parasitic elements of the plurality of parasitic elements, each load circuit further being connected to the ground plane.
