Abstract
In the field of wideband directional antennas employing linear polarization, and in particular in the context of amplitude goniometry systems, polarization purity defects lead to deformation of the radiation diagrams that increases with the elevation, inducing degraded detection system location performance. An antenna is provided operating with linear polarization and having radiating elements of 'sinuous' shape inscribed within a circle, and includes radiating elements printed on the two faces of a support, the elements of the first face being deduced from those of the other face by a rotation.
