ABSTRACT:
An elementary antenna embodies a constant thickness dielectric substrate having on one side a conductive metal layer forming a ground plane and on its other side a radiating patch electrically connected to a feed line. The patch is formed by a conductive loop of constant width l surrounding an inner parasitic patch which is not fed and is separated from the inner parasitic patch by a closed continuous slot of constant width e adapted to bring about coupling between the loop and the inner parasitic patch.
