Abstract
A directional antenna system. The invention includes four independent antenna elementsand, each configured to provide a specific set of characteristics. When used for reception, the outputs from these elements are uniquely related and processed to determine the direction of a source emitter relative to the positioning of the elements independent of the polarization of the radiated energy.
