Abstract
A reflector array antenna is 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. Each subarray sums the collected signals as a function of a chosen first phase law so that they correspond to a chosen source pointing direction, applies a chosen phase shift to the summed signals, and distributes the phase-shifted signals between the radiating elements as a function of a chosen second phase law so that the radiating elements of each subarray radiate them in a pointing direction of a chosen area. The combining and distribution are effected separately and the subarrays are therefore of a nonreciprocal type.
