Abstract
A radar system for detecting the environment of a motor vehicle includes an antenna assembly comprising plastic and including one or more individual antennas for transmitting and/or receiving radar signals. A circuit board includes at least one area that is permeable by radar waves. At least one high-frequency component is coupled to one side of the circuit board and includes at least one radiating element for direct emission or receipt of radar waves in the direction of the circuit board in the least one area that is permeable by radar waves. The antenna assembly is disposed on the other side of the circuit board opposite the at least one high-frequency component. The antenna assembly includes a coupling/decoupling point disposed in the at least one area of the circuit board permeable by radar waves.
