Active ultrahigh frequency network, comprising imbricated network slots (21, 22) coupled with independent phase displacement cells (D). The slots are orthogonal to the slots of the other network. The slots are configured in a mass plan (23) excited by coupling lines (24) linked to the phase displacement cells. The network comprises at least three levels of ultrahigh frequency circuits. The first level, at the front is susceptible to be illuminated by an ultrahigh frequency (1) carrying orthogonal slots and coupling lines. The other two levels comprise phase displacement circuits in semi-conductors. Each of the levels is dedicated to a polarization. The coupling lines are situated in the median line (30) of a layer of dielectric equipment (31) limited by the slots plan and by a plan of mass. These lines are linked to other levels by metallized gaps (25). These gaps surround each phase displacement cell and are programmed in the dielectric equipment to form an electromagnetic shield. There is a reflector (4) and an ultrahigh frequency wave (1) illuminating the reflector. The reflector allows for the formation of a Cassegrain type antenna.
