Abstract
A radar system including a circuit board and a molded part having an antenna, wherein the connection between an emitting or receiving element of a high-frequency component and the antenna on an upper side of the molded part is realized by inner waveguides, the emitting or receiving element configured to emit in the direction or receive from the direction of the circuit board, the circuit being permeable by radar waves in the region of the emitting or receiving element, the molded part being arranged on a side of the circuit board opposite the high-frequency component and partially and conductively connected to said circuit board, at least one hollow waveguide is formed by a depression on the side of the molded part facing the circuit board and a metallized surface of the circuit board, and said at least one waveguide is fed from a permeable location of the circuit board.
