Abstract
New type of planar antenna of microwaves appropriate for operating in linear and circular polarization, free of welds and floating potentials, and therefore free of electrostatic discharges and problems related to passive intermodulation products, whose application is of particular interest in aircraft and space technologies. The antenna consists in the interconnection of a microstrip radiator with a spiral antenna of wires. For certain applications wherein the radiators are arranged in a same plane, the radiating effect of the patch may reduce the size of the spiral.
