Abstract (en)
[origin: EP2120281A1] The system has an antenna including a control unit coupled with a power supply unit such that sub-sets of radiating elements in a radiating element array of the antenna are successively powered to form beams illuminating one of sub-spots (A1-A3) in each of spots of a coverage obtained according to an initial reutilization scheme. The obtained coverage is equivalent to a reutilization scheme of reutilization factor equal to a product of an initial reutilization factor and number of sub-spots in each spot.
