Abstract: A radar sensor and a radar antenna are for monitoring the environment of a motor vehicle. A compact construction is achieved by the planar array of both the control circuit and the radar antenna, so that the radar sensor may be located, for example, in the area of a motor-vehicle bumper. Example configurations consist of the separate line support for arranging lines to transmit high-frequency signals between the control circuit and the radar antenna and the configuration of the radar antenna as a Rotman lens, in relation to the signal propagation times and the layered arrangement of Rotman lens and group antenna.

Abstract: A method for making a cover for an integrated optical circuit, a cover for an integrated optical circuit, and an integrated optical circuit made with this cover are proposed. The method serves to minimize the effort and expense in integrating optical components in fiberoptical systems. An optical element 29 is placed in a molding die (10) with adjusting elements (13) that adjust the optical component (29) in its position, and a curable liquid is cast all around the optical component (29), and after it solidifies, this liquid forms the cover (25).
