Patent ID: 7142164

Claim:
A reflector array antenna divided into independent subarrays each comprising: at least two radiating elements adapted firstly to collect signals delivered by a source and having at least one chosen first polarization and secondly to send phase-shifted signals having at least one chosen second polarization orthogonal to the first polarization, combination means adapted to sum said collected signals as a function of a chosen first phase law so that they correspond to a chosen source pointing direction, phase control means adapted to apply a chosen phase shift to the summed signals, and distribution means adapted to distribute said phase-shifted signals between said radiating elements as a function of a chosen second phase law so that said radiating elements of each subarray radiate them in a pointing direction of a chosen area with the second polarization, in which antenna said combination means and said distribution means are separate so that said subarrays are of a nonreciprocal type.
