Abstract: An antenna device for automotive radar applications includes a printed circuit board having a front face and a back face and an electronic component which is interconnected to the printed circuit board and an antenna layer having a front face and a back face, which back face is interconnected to the front face of the printed circuit board. At least one waveguide aperture is interconnected to the front face of the antenna layer and is communicatively connected to the electronic component by at least one waveguide channel, wherein the at least one waveguide channel comprises a conductive surface for guiding an electromagnetic field between the electronic component and is formed by a recess arranged between the back face of the antenna layer and the front face of the printed circuit board.

Abstract: An antenna device for automotive radar applications including an antenna assembly which comprises a front face in which at least one antenna aperture is arranged, configured to receive an incoming signal in form of primary rays impacting in the at least one antenna aperture. The front face of the antenna assembly further includes adjacent to the at least one antenna aperture scattering elements by which primary rays, impacting an area of the scattering elements, are at least partially reflected by the scattering elements and thereby separated into first secondary rays and second secondary rays, such that the first secondary rays and the second secondary rays cancel out each other at least partially by interference.

Abstract: A sanitary insert unit (6) is provided having an insert housing (2) which can be mounted on or in a water outlet (3) of a sanitary outlet fitting and in the housing interior of which there is provided a liquid path that channels water flowing through the housing interior. A jet splitter (9, 10) with a plurality of splitter openings (11, 13) is provided in the liquid path, and the splitter openings divide the through-flowing water into a plurality of individual jets. At least one grid or mesh structure (14, 15) follow the jet splitter (9, 10) in the liquid path, and at least one bypass duct (16) which bypasses the liquid path at least in certain portions is provided. The bypass duct (16) is formed as a nozzle for generating at least one accelerated liquid jet, and for this purpose, the at least one bypass duct (16) has a tapering clear duct cross section at least in a sub-portion.
