Radio frequency antenna with reflector, able to cover several separate geographical zones. The reflector consists of several sectors (R1, R2) with separate foci (F1, F2) which are obtained from a hypothetical basic reflector (P), by exerting rotations (r1, r2) and possible translations (t1, t2, t3) in order finally to select, on a single surface, only the sectors (R1, R2) which are separated from one another by a predefined line (L). <IMAGE>
