摘要

The antenna comprises sub-arrays (10) which are provided with a transmission line excitation system (13) and a system of electrically-controlled phase shifters (15) feeding planar discrete radiators (14), mounted in the antenna aperture and spaced by several wavelengths. The radiators make up a radiating system (11) in each sub-array, for which a common beam steering system (17) is used. The total number of outputs of the excitation system is equal to the number of phase shifters, while four inputs (16) are provided. Preferably a correction block is used, in conjunction with the beam steering system, to modify the radiation pattern of the antenna. An Independent claim is included for a
