Abstract: The invention relates to a wire antenna suitable for operating in at least one frequency band, including a plurality of stacked layers, including at least one radiating element placed on a support layer, said support layer being placed on a spacing substrate placed on a reflective plane, characterised in that it includes at least one resistive grille having a resistive surface with predetermined resistance, including at least one set of repetitive, non-contiguous empty patterns, said grille being placed between the spacing substrate and the reflective plane.

Abstract: A horn antenna including a ground plane delimiting an upper half-space, a horn forming one end of a waveguide, the horn crossing through the ground plane so that a mouth of the horn is arranged at a predetermined height above the ground plane in the upper half-space. The antenna is characterized in that it includes at least one resistive film arranged around the horn, parallel to an upper face of the ground plane, the resistive film having an electrical resistance suitable for limiting creeping waves.
