Antenna has linear polarization, direction, broadband, has high polarization purity.

In the field of broadband directional antennas operating in linear polarization, and in particular within amplitude goniometry systems, polarization purity defects result in deformation of the radiation patterns inducing degradation of system performance location detection. The antenna of the present invention is an antenna operating in linear polarization and radiating elements of sinuous shape inscribed in a circle, and includes printed radiating elements on both sides of a support, the elements of a first face deducting those of the other side through rotation.
