The system has reception and transmission antennas provided with reflectors configured for covering an area with grids of spots, where each antenna has a set of radiating elements producing spots. The radiating elements are arranged so as to align spots of one of grids generated by one of the antennas along orthogonal axes so that points are located at equidistant from centers (311-314) of adjacent spots. Spots of another grid generated by the antenna are centered on the points. The spots of the former grid have same dimension as spots of the latter grid. |
