Abstract
A radar system for detecting the surroundings of a motor vehicle, the radar system includes a plastic-based antenna having a front side facing a cover. The plastic-based antenna has a plurality of individual antennas for transmitting and/or receiving radar signals to detect objects and/or determining angles thereof. The front side between the individual antennas is configured to be at least partially not reflective on a surface thereof such that interference waves on the surface of the plastic-based antenna and/or reflections between the plastic-based antenna and the cover are suppressed or the negative effects thereof on the determination of angles are at least reduced.
