ABSTRACT:
An antenna providing circular polarization for received and transmitted signals. The antenna comprises a vertical conductive surfaces oriented to form a closed structure and horizontal conductive surfaces forming a top face of the closed structure. Connection of selected vertical panels to a feed and ground, causes current flow in the vertical and horizontal surfaces that results in a circular polarized signal.
