Abstract (en)

An elementary antenna (1) including a dielectric substrate (2) of constant thickness hugged, on one face, by a conductive metal layer (3) forming an earth plane and on its other face by a radiating element (4) connected electrically to a supply line (5), characterised in that the element (4) is formed by a conductive loop (6) of constant width l, surrounding an unsupplied internal parasitic element (7) whilst being separated from this internal parasitic element by a continuous slot (8) closed on itself and of constant width e suitable for ensuring coupling between the loop and the internal parasitic element. <IMAGE>
