A coupling structure for crossing three transmission lines millimeter-wave or centimeter-wave signals a signal conductor layer of a circuit substrate, the coupling structure comprising three planar cross-couplers, and from each of the three cross-couplers two input/output points of the cross-coupler being connected clockwise in succession in the plane of the cross-coupler, to respectively one input/output point of a respective other of the three cross-couplers.

Coupling structure for crossing transmission lines

A radar sensor for motor vehicles includes a printed circuit board which carries the mass and antenna structures of the radar sensor, and includes a housing accommodating the printed circuit board, the housing being formed on a transmit and receive side of the radar sensor by a radome which is transparent to radar radiation, characterized in that the radome has an essentially plane wall oriented obliquely to the printed circuit board.

Radar sensor including a radome

A radar sensor includes: a radar antenna, a radar lens and a funnel element between the radar antenna and the radar lens. The funnel element includes a material which absorbs the radar radiation emitted by the radar antenna.

A high-frequency circuit is described as having lines crossing each other on a printed circuit board for high-frequency signals, wherein the sections of the lines, lying on both sides of a crossing point as well as a coupler forming the crossing point are situated in a common plane on the printed circuit board and the sections of the lines are connected to four ports of the coupler situated in a quadrangle, which are connected to one another via a plurality of coupling paths in such a way that the components of a signal supplied at a port, which propagate on various coupling paths, interfere destructively at the adjacent ports and constructively at the diagonally opposite port.
