The antenna (1) has at least one region (4) which is transparent for optical waves and which reflects radar waves. The antenna (1) may comprise an optically transparent material on whose surface which reflects the radar waves there is a metallic film (8) with a net structure, allowing the passage of light waves, and on whose remaining surface, the metallic film is homogeneous (7). The edge length of the bridges of the metallic film (8), in the net part, pref. have a wavelength about one tenth of the radar waves. On the bridges a layer of In2O3 or SnO2 may be deposited. @(6pp Dwg.No.1/5)@
