Abstract: An ultrasonic phased array sensor with a multi-layer structure. At least one first layer has a membrane. At least one second layer has a piezoelectric substrate. At least one third layer has a plurality of electrical contacts. The electrical contacts are applied independently of one another on a surface of the piezoelectric substrate.

Abstract: A radome subassembly for a radar sensor for motor vehicles, which radar sensor encompasses a radar-frequency printed circuit board having at least one antenna and a radar-frequency printed circuit alongside the antenna, the radome subassembly encompassing: a radome for covering the antenna side of the radar-frequency printed circuit board; and an absorber for radar waves in order to shield the radar-frequency printed circuit, the absorber being disposed in front of an inner side of the radome, the absorber leaving a region next to the absorber, in front of the inner side of the radome, open for a main antenna lobe of the at least one antenna, the absorber being fastened on the radome, and the radome subassembly having at least one elastic plastic element by way of which the absorber is braced movably against the inner side of the radome. A radar sensor having the radome subassembly is also described.

Abstract: A vehicle includes a body having a body outer element that has an external surface, and a radar module having a radar sensor, a housing that accommodates the radar sensor and that has a housing opening situated in the direction of detection of the radar sensor, and a radome fastened on the housing that closes the housing opening in the manner of a cover. The radome forms a part of the external surface of the body outer element.
