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.

The disclosure provides a protection structure of an object detection device of a vehicle. The protection structure includes: a bumper provided in a first direction, which is an object detection direction with respect to a radar device attached to a vehicle body frame via a support member; and a cover member covering the radar device. The cover member includes: a base part connected to the bumper; and an extension part extending from the base part in a second direction opposite to the first direction. The extension part is configured to abut on the vehicle body frame before the base part contacts the radar device or the support member in response to the bumper being displaced in the second direction due to an action of an external force.

An autonomous vehicle includes a vehicle body having a receiving device configured to receive an object to be transported, a chassis having at least one driven wheel, and at least one sensor device having a detection region surrounding the autonomous vehicle for recognizing obstacles which enter the detection region in the immediate surroundings of the autonomous vehicle.
