Abstract
The antenna with shared feeds for generating multiple beams includes a plurality of identical individual feeds spaced apart by a constant pitch, wherein the individual feeds are associated in identical subnetworks around a central individual feed, each subnetwork being intended to synthesize a beam, the individual feeds of each subnetwork being phase-coupled together by electromagnetic coupling, and two successive subnetworks include at least one individual feed in common and are offset by a distance corresponding to a predetermined number of pitches greater than or equal to one, being applicable in particular to the field of satellite telecommunications.
