1. Radiofrequency antenna array comprising several waveguide devices for transmitting and/or receiving electromagnetic signals, the radiofrequency antenna array comprising several ridges, each waveguide device comprising:
at least one inner wall;
a first layer comprising at least one radiating element, each radiating element including a downstream opening in a direction of propagation of said emitting signals,
a fourth layer comprising at least two upstream openings in the direction of propagation of said signals during emission linked to said downstream opening so that said emitting signals are transmitted from said upstream opening to said downstream opening;
a second layer for connecting the first layer to the fourth layer, said second layer forming a beamforming network,
wherein the arrangement of ridges in the downstream openings of each waveguide device comprises no more and no less than three ridges,
and wherein the number of ridges in each upstream opening of at least one waveguide device is different from three,
and wherein in each waveguide device, a first ridge in the downstream opening extends in said direction of propagation to the upstream openings so as to form a septum.
