A radiating element of an antenna includes at least one wire-like nanostructure, each wire-like nanostructure extending in the same direction, called common direction, between a first end and a second end, and an inductor connected to each first end of a nanostructure, the inductor being formed from a first conductive material, the inductor extending in a plane normal to the common direction, the first conductive material having an electrical conductivity that varies under the effect of a variation of an electric field applied within the first conductive material.
