Abstract:
1. An omni-directional, orthogonally propagating, one-quarter wavelength folded loop antenna system enabled with polarization diversity, comprising: a folded loop antenna fabricated from a conductive medium, the folded loop antenna comprising an upper horizontal, a lower horizontal and a vertical antenna element, wherein the antenna has an overall length that is approximately one-fourth a wavelength at a required frequency; a ground plane in contact with the folded loop antenna, wherein the ground plane has a minimum length of three-sixteenths of a required wavelength and further comprises a vertical trace in contact with the upper horizontal antenna element, the vertical trace serving as an antenna return; a conductive plane situated in proximity to the folded loop antenna, located near an antenna feed and the antenna return of the folded loop antenna, wherein the conductive substance is electrically isolated from the ground plane and the folded loop antenna; the conductive plane being a minimum of one-half inch wide and having a length that extends approximately the length from the upper horizontal element to the lower horizontal element; a semiconductor device in electrical contact with the ground plane and the conductive plane; and a processing means in electrical communication with the semiconductor device, wherein the processing means controls the activation and deactivation of the semiconducting device.
