A reflector antenna network has phase control.

The reflector system of this antenna has a reflective surface supported by a frame (2) and illuminated by a primary UHF source (4). It comprises on the reflecting face a large number of elementary sources each formed by a radiating element loaded by a controllable phase shifter placed on a shorted line. The elementary sources are arranged in several on insulating boards (1) lining the reflecting face of the reflector array, their frame-facing wafer (2) and which each carry, on at least one face, a conductive printed circuit ( 5) forming a pattern consisting of several radiating elements (7) laterally directed away from the armature (2) and placed side by side at the head of a slot line (8) short-circuited end, the least one diode (9) to short-circuit slot line, insulated conducting tracks (10) carrying the bias voltage short-circuit diodes (9) and a circuit (11) for controlling polarizations of the short diodes -Circuit (9).
