The cover, designed to conceal a radar antenna on a motor vehicle, consists of front (1) and rear (2) elements made from a material that is transparent to electromagnetic waves, and a cellular component (3) between them in the shape of a motif such as the vehicle manufacturer's logo. The cover, designed to conceal a radar antenna on a motor vehicle, consists of front (1) and rear (2) elements made from a material that is transparent to electromagnetic waves, and a cellular component (3) between them in the shape of a motif such as the vehicle manufacturer's logo. The cellular component has radioelectric characteristics close to those of air, and can be of a foam with a coating of a shiny material containing conductor wires lying perpendicular to the electromagnetic wave polarization in two layers offset by a half-pitch.
