The invention relates to a wire antenna adapted to operate in at least one predetermined frequency band, comprising a plurality of superimposed layers, comprising at least one radiating element placed on a support layer, wherein the support layer is placed on a spacer substrate, and wherein the spacer substrate is placed on a reflector plane comprising at least one resistive layer between the support layer of the radiating element(s) and the substrate spacer, while the resistive layer comprises at least two sets of nested resistive patterns. This antenna is such that the sets of resistive patterns have resistance values gradually varying between a central antenna point and an outer edge of the antenna, in order to achieve a resistance gradient.

Broadband wire antenna with resistive patterns having variable resistance

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.
