Antenna system with two grids of spots with nested complementary meshes

Abstract

An antenna system is able to cover a geographical zone with two grids of spots with nested meshes, shifted one with respect to the other. The multi-beam system covers a geographical zone decomposed into a plurality of spots, the antennas each comprising an array of radiating elements able to receive and/or to transmit radioelectric signals, and being configured so as to cover, in reception and/or in transmission, the zone with two grids of spots, several spots of the first grid, generated by a first antenna, being positioned according to a first geometric pattern, so that points are situated substantially equidistantly from several adjacent spots, several spots of the second grid, that are generated by a second antenna, being positioned according to a second geometric pattern chosen as a function of the first geometric pattern, such that several spots of the second grid are centered on the points.
