Abstract:
An antenna comprising a set (30; 30.sub.1, 30.sub.2) of static radiating elements commanded to transmit a beam in variable directions relative to a given central direction and reflector means (34, 44; 34', 44') including two reflectors (34, 44; 34', 44') having a common focus (40), the first reflector (34, 34') receiving the beam transmitted by the set of radiating elements and the second reflector (44; 44') receiving the beam reflected by the first reflector, characterized in that the focal length of the first reflector (34, 34') is greater than the focal length of the second reflector (44', 44') so that the exit beam of the antenna has an inclination to a predetermined direction (38) which is greater than the inclination .THETA. relative to the given direction (38) of the beam transmitted by the radiating elements (30).
