ABSTRACT:
An antenna lens, in particular for a motor vehicle radar system, has in a plane perpendicular to the optical axis of the antenna lens at least a first and a second lens region, the lens regions being configured such that electromagnetic waves are concentrated or scattered in a first manner upon passage through the first lens region and in a second manner upon passage through the second lens region. The lens regions have different polarization-dependent permeabilities for electromagnetic waves. A motor vehicle radar system having an antenna lens of this kind is also described.
