Abstract: The invention relates to hybrid insulation for a recreational vehicle, in particular a motorhome or a caravan, with at least one mat element based on a plastics foam mat. It is proposed that at least one cover element based on a fiber material is provided. Furthermore, a recreational vehicle, in particular a motorhome or a caravan, comprising such a hybrid insulation is provided. Furthermore, a method for adapting an insulation for a recreational vehicle, which insulation has mat elements based on a plastics foam mat, is provided, wherein a part of the mat elements is replaced and optionally supplemented by cover elements based on a fiber material to form a hybrid insulation according to any one of claims 1 to 8.

Abstract: A method for producing a vehicle part with an integrated antenna element includes providing a plastic substrate by a molding process, providing a coating layer by a film coating process, and providing at least one antenna element disposed between the coating layer and the plastic substrate.

Abstract: A method and corresponding devices for monitoring the performance of a radar system (2, 4) which is equipped with a shield 2 (radome) to protect it against weather influences are described. For this purpose, a part of the radiated radar signal is modified and fed as a monitor signal to the reception system after interacting with a coating (5) which is possibly present on the radom (2). Influences of a damping or reflecting coating (5) on the radom (2) change the monitor signal. By analyzing these changes it is possible to draw conclusions about the coating of the damping or reflection of the radar signals which is caused by the coating (5).

Abstract: A method for providing an inverted-L antenna in motor vehicle includes providing a microstrip line and providing a laminar motor vehicle component including an electromagnetically transparent material, the laminar component forming part of an outer skin of the motor vehicle. The inverted-L antenna is disposed under the laminar motor vehicle component so as to be electromagnetically coupled to the microstrip line in a contactless manner.
