1. A radar system for detecting the surroundings of a motor vehicle, the radar system comprising:
a plastic-based antenna having a front side facing a cover, the plastic-based antenna having plurality of individual antennas for transmitting and/or receiving radar signals to detect objects,
wherein the front side of the plastic-based antenna is configured to be at least partially not reflective on an upper surface therof,
wherein the front side of the plastic-based antenna has a non-planar reflective surface, individual antennas among the plurality of individual antennas have a concentration in the vertical dimension with a main beam direction approximately at elevation 0°, and the non-planar reflective surface surface does not run linearly with respect to vertical sections.
