ABSTRACT:
An antenna group comprising a plurality of spiral antennas occupies a circular space. The spiral antennas are radially symmetrically arranged about a point at the center of the circle. Each spiral antenna is deformed to occupy a substantially all of the area within a sector of the circle. The antenna may be used for detection of circularly-polarized waves of either polarization sense, or may operate with phase-sensing means to locate the source of incoming electromagnetic radiation.
