Abstract
A radar sensor for reception of radar waves. The radar sensor includes at least one control unit and at least one circuit board. The at least one circuit board includes a substrate and a structure that is arranged on the substrate and has a multiplicity of metallization structures. The radar sensor is configured to be arranged on a radome in such a manner that the substrate is arranged on a side facing away from the radome and the structure is arranged between the radome and the substrate. The at least one control unit is arranged on a side of the substrate facing away from the radome and is in communicative connection with the at least one circuit board. At least one opening is made in the structure and only ambient medium is present between the radome and the at least one opening.
Claims10
A radar sensor to transmit and receive radar waves, the radar sensor comprising:
- at least one control unit;
- and
- at least one circuit board comprising a substrate and a structure that is arranged on the substrate and has at least two metallization structures,
- wherein the radar sensor is configured to be arranged on a radome such that the substrate is arranged on a side of the at least one circuit board facing away from the radome and the structure is arranged between the radome and the substrate,
- wherein the at least one control unit is arranged on a side of the substrate facing away from the radome and is in communicative connection with the at least one circuit board,
- wherein at least one opening is made in the structure,
- wherein only an ambient medium is present between the radome and the at least one opening, and
- wherein a metallization for shielding from electromagnetic radiation is arranged on an outside of the structure facing away from the substrate.
