摘要

The antenna of the invention can be oriented, directional, and capable of operating either in transmission or reception, or both. & br / the antenna comprises at least one reflector, at least one source of electromagnetic radiation comprising means for exciting the source according to two orthogonal linear polarizations, and the mechanical means for positioning and holding of the source and reflector. According to the invention, the orientation of the antenna is split up into a misalignment and a rotation around a privileged direction of propagation of the radiation, and the mechanical means make it possible to carry out this rotation, while maintaining the source is fixed, thus retaining the orientation of the axes of polarization orthogonal linear. & br / in a preferred embodiment, the antenna of the invention comprises a parabolic reflector and an auxiliary reflector hyperbolic arranged in a cassegrain geometry, and the mechanical means make it possible to carry out a rotation of the two reflectors around the privileged direction of the radiation, while maintaining the source is fixed, thus retaining the axes of the orthogonal linear polarizations of the beam. & br / applications in the radar, television broadcasting by satellite, and in telecommunications, by radio with frequency re-use by polarisation diversity, particularly advantageous in aerospace applications or airborne.
