Abstract

The invention relates to a reflector antenna for bundling radar waves for distance sensors, especially distant view radar sensors for a motor vehicle. Said antenna comprises a main reflector and optionally one or more subreflectors. The main reflector and/or the optionally one or more subreflectors comprise at least one impurity that effects the broadening of the individual antenna beam, preferably a plurality of antenna beams, and/or a reduction of a side lobe of an antenna beam, preferably a plurality of antenna beams.
