Claim:
1. A stacked parasitic array, comprising: a first parasitic antenna array comprising a substrate, a centrally-driven monopole element, a first ground plane, a plurality of parasitic monopole elements, and a plurality of load circuits, said centrally-driven monopole element being connected to said substrate to radiate electromagnetic energy in an omni-directional radiation pattern, said first ground plane being connected to a surface of the substrate, said plurality of parasitic monopole elements being connected to the substrate and substantially surrounding the centrally driven monopole element, said plurality of load circuits being connected to the plurality of parasitic monopole elements and being connected to the first ground plane; and a second parasitic antenna array comprising a second ground plane, the second parasitic antenna array and the first parasitic antenna array being arranged in a stacked configuration forming the stacked parasitic array with the second ground plane of the second parasitic antenna array being orthogonal to a parasitic monopole element of the plurality of parasitic monopole elements of the first parasitic antenna array, said stacked parasitic array being configured for multiband operation.
