The elementary antennaincludes: two cross-shaped slotsdefining four half-slots; for each half-slot, excitation striplines, the first striplinebeing connected to a first viaand the second striplinebeing connected to a second via; an integrated circuitdelivering a plurality of ports; for each half-slot, tracks for feeding the strips, the first trackrunning from a first portto the first viaand the second trackrunning from a second portto the second via, the first and second ports being two successive ports of the integrated circuit, differentially connected to a transmitter/receiver channel by first and second power lines situated inside the integrated circuit, the lines and tracks running so that there is no crossing of the respective routes thereof.
