Abstract:
A transmit and receive antenna, for a telecommunications system, for communicating via signals with a target or source area having a position which is variable relative to the antenna, the antenna having a radiation pattern and including, in combination: guide means (80, 82) for pointing the antenna towards the target or source area; and a plurality of radiating elements (74, 76),the antenna being characterized in that the target or source area is of large extent, and in that the radiating elements are associated with power control means for modifying the radiation pattern of the antenna, as a function of the varying relative position of the antenna and the target or source area, to match the pattern to the shape of the target or source area, as seen by the antenna, so as to maintain communication between the target or source area and the antenna regardless of the varying position of the antenna relative to said area.
