1. Antenna system comprising:
an antenna; and
a device for a passive angular deflection of a main radiation lobe of said antenna, a reference frame being attached to the antenna system, the X and Y axes of the reference frame lying in a radiation plane of the antenna and the Z axis of the reference frame being normal to the radiation plane, an origin of the reference frame coinciding with a geometric center of the radiating plane of said antenna, wherein the device comprises a lens having a constant thickness and having a progressive relative permittivity between an inner edge of the lens located on an inner edge located in the vicinity of the geometrical center of said antenna and an outer edge of the lens located in the vicinity of a periphery of said antenna, a profile of the relative permittivity as a function of a distance to the geometrical center of said antenna being adapted in such a way that the lens deflects the main radiation lobe of said antenna by a predefined deflection angle over at least one portion of an operating frequency band of the antenna.
