Abstract
A small antenna comprising an unequal current density center-fed dipole employing a conductive trace and a ground plane counterpoise positioned substantially perpendicular to each other. According to one embodiment, a conductive trace is etched onto a dielectric substrate to form a printed circuit. According to a further embodiment, the conductive trace has two sets of orthogonal components; one set of components captures the desired electric field polarization and the second set of components cancels out the undesired cross polarization. A portion of a signal received on the first set of components adds together to produce a desired resultant vector and a portion of the signal received on the second set of components adds together to cancel out the undesired vector.
