Abstract (en)
This invention concerns an antenna system comprising:- a wave launcher (10, 210);- a deflection system configured to deflect the wave and comprising at least one planar deflector (20, 30; 210, 220), said planar deflector comprising a plurality of inclusions (300) configured to add a phase gradient to the wave incident on said deflector;- according to the invention, said inclusions are configured to work in an environment with refractive index greater than 1 and wherein, in addition, one or more matching devices are included at the outlet from and/or inlet to the deflector.
