1. An array antenna, comprising:
a plurality of mechanically separate radiating panels arranged side-by-side, each radiating panel comprising a plurality of radiating elements,
means for applying a shaping to radio frequency signals transmitted by or received from each radiating element, and
a device for managing the radio frequency signal shaping application means, wherein the shaping application means are configured to apply, to the signal transmitted by or received from each radiating element, a complex shaping coefficient corresponding to a sum of at least:
a shaping coefficient (Wco) making it possible to orient a maximum gain of the antenna in a given direction, and
at least a negative of a shaping coefficient (Wc) making it possible to orient the maximum gain of the antenna in the direction of a side lobe resulting from differences between the radiating panels of the array antenna.
