Beschreibung
Zusammenfassung:	The invention relates to a radiofrequency antenna comprising a chassis (26) and an emission surface supporting a set of radiating antenna elements, each radiating in a unique emission direction, characterized in that each antenna element is at least partially movable relative to the emission surface to modify its specific emission direction and in that it comprises means for moving the antenna elements in a coordinated manner along said surface to form, from the elementary waves produced by the antenna elements, a coherent wave propagating in a direction that is angularly offset relative to the normal to the emission surface.
