Abstract
An antenna structure is disclosed that includes a first antenna extending from a substrate, a second antenna formed on the substrate, and first and second parasitic elements formed on the substrate. The first antenna provides an omni-directional radiation pattern in the azimuth plane for vertically polarized signals, and the second antenna provides an omni-directional radiation pattern in the azimuth plane for horizontally polarized signals. The parasitic elements absorb and re-radiate electromagnetic waves radiated from the second antenna.
