A device includes a test enclosure defining a cavity forming an anechoic chamber, having a test probe placed inside the cavity. The cavity comprises an aperture against which the radiating surface of antenna is positioned. The device includes a microwave-frequency test signal generator and a receiver for microwave-frequency signal emitted by the antenna under test and for measuring its amplitude and its phase in relation to a reference. Depending on the depth of the cavity and the dimensions of the radiation pattern of a test probe, the device comprises one or more test probes placed in fixed positions in the cavity or a mobile probe that can be positioned in various locations of the cavity, the probe or probes being configured and arranged to illuminate the whole active surface of the antenna and that the radiation pattern of each radiating element illuminates at least one test probe.

A system including a first polarization element configured to linearly polarize at least one beam in open space, a processing device configured to receive linearly polarized beams at an input, downline from the first polarization element, a first polarization switch downline from said processing device, wherein the processing device carries out an identical processing on two states of a same input beam. The processing device includes a multiple delay creation device with polarization switches, and the multiple delay creation device includes, on two routes (j&equals;1,2): n polarization switches CP , (1&lE;i&lE;n); n polarization splitters/recombiners SP (1&lE;i&lE;n); and n delay devices R (1&lE;i&lE;n).
