Abstract
The radio antenna comprises a substrate formed of a dielectric material; a ground plane made of an electrically conductive material, the ground plane being arranged on a first face (F) of the substrate; a resonator configured to convert an incident electrical signal into an electromagnetic wave. The resonator includes a first element (E) having a first characteristic impedance and a second element (E) having a second characteristic impedance that is higher than the first characteristic impedance. The first element (E) is configured to receive the incident electrical signal, the first element (E) is formed by a strip of electrically conductive material, the strip being arranged on a second face (F) of the substrate opposite the first face (F). The second element (E) is formed by a rectilinear segment, cut in the ground plane and separated from the rest of the ground plane by a slot () of fixed width. The second element (E) is electrically connected to the ground plane at a first end of the segment and electrically connected to the first element at a second end of the segment by means of a via () passing through the substrate.
