Patent ID: 8830132

Claim:
A parasitic antenna array, comprising: a substrate, the substrate including a first surface and a second surface, the second surface being disposed generally opposite the first surface; a monopole element, the monopole element being connected to the substrate, the monopole element configured for radiating electromagnetic energy in an omni-directional radiation pattern; a ground plane, the ground plane being directly connected to and located on and in proximity to the second surface of the substrate; a plurality of parasitic elements, the plurality of parasitic elements being connected to the substrate and extending from the second surface of the substrate, through the substrate and out of the first surface of the substrate; and a plurality of load circuits, the plurality of load circuits being connected to the plurality of parasitic elements, the plurality of load circuits further being directly connected to the ground plane, the plurality of load circuits and the ground plane being in proximity to the second surface of the substrate, each load circuit of the plurality of load circuits including a first diode connected to a parasitic element of the plurality of parasitic elements to the ground plane and a second diode connected to the parasitic element and a capacitor, the capacitor connected to the ground plane.
