Abstract: A radome for a radar device of a vehicle includes a front member made of a radar-transparent resin having a first homogeneous electromagnetic thickness. A second member is also made of a radar-transparent resin having a second homogeneous electromagnetic thickness. A first gap is positioned between the front member and the second member of a third homogeneous electromagnetic thickness (T3), either filled by a gas or a radar-transparent resin. Either: the front member, the second member and the first gap are each individually optimized for radar performance metrics; or a unit consisting of the front member, the second member and the first gap is optimized for radar performance metrics.

Abstract: A vehicle body panel is provided and includes a plurality of components fixedly attached to the support structure. The plurality of components may include at least two of the following: at least one navigation unit, at least one communication unit, at least one antenna unit, at least one lighting unit, at least one signalling light unit, at least one illumination unit, at least one heating unit, at least one cleaning unit, at least one design element, at least one lighting cover lens, at least one sensor cover lens, at least one sensor housing, at least one radome, at least one safety unit, at least one camera unit, at least one parking system unit, at least one emblem unit and at least one sensor unit.

Abstract: A multi-layer panel structure for a vehicle is provided, and includes a first layer of an optically transparent material adapted to serve as a light guide. The first layer has an upper surface., a lower surface, and edges, and is configured to receive light from at least one light source via at least one edge. The first layer further includes at least one optical element for outcoupling light at least from an upper surface of the first layer. The panel structure further includes an upper second layer disposed on the upper surface of the first layer, and a lower second layer disposed on the lower surface of the first layer. Each are arranged to cover the whole of the upper and lower surface of the first layer in an uninterrupted, continuous fashion. Both are of a second optically transparent material having a refractive index lower than the first layer.
