Abstract
A planar antenna comprising a spiral conductive surface comprising an inner spiral segment and an outer spiral segment. A shorting leg for connection to a ground plane and a feed leg responsive to the antenna signal (in the transmit and the receive modes) extend downwardly from the plane of the spiral segments. Performance characteristics of the antenna are responsive to the configuration and spacing of the spiral segments and the distance between the antenna and the ground plane.
