Abstract:
1. Reflector array antenna (A), characterized in that the antenna comprises: a source (S) adapted to deliver signals in the form of waves, at least two different and independent reflector arrays (RRi) each comprising at least two phase-shifter cells (CD) adapted to impose on said waves delivered by the source (S) a chosen phase-shift and a chosen frequency-phase dispersion, said chosen phase-shift and/or said chosen dispersion varying from one reflector array (RRi) to the other of said reflector arrays, and a loading device (DC) coupled to said reflector arrays (RRi) and adapted to alternately place each of said reflector arrays in a chosen position relative to said source (S) so that the waves that said source delivers are subjected to the phase-shift and the frequency-phase dispersion imposed by said phase-shifter cells of said placed reflector array (CD), so as to be reflected in a chosen direction.
