Abstract
An antenna for use in navigation and communication satellite systems, which has a hemispheric response pattern. The antenna is constructed of a pair of conductors formed into a planar spiral and backed by a cavity. Radial elements extend orthogonal to the spiral axis outwardly around the periphery of the spiral. A crossed pair of parasitic elements is located above and coplanar to the spiral plane.
