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 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.

High-frequency circuit having crossed lines

Radar sensor having a mixer for mixing a received signal with a reference signal and having a device for compensating interference signals which would overload the mixer, wherein the device for compensating the interference signals has an adjustable reflection point at the reference input of the mixer.

Radar sensor having interference signal compensation

In a multibeam radar sensor apparatus having at least two transmission/reception channels, whose signal paths each include an antenna and a mixer, at least one first mixer is configured bidirectionally as a transfer mixer, and at least one second mixer is switchable from a first into a second operating state; in the first operating state, the mixer is bidirectionally configured as a transfer mixer, and in the second operating state, the mixer being configured in an at least approximately isolating manner as a receiving mixer. In addition, in a method for determining a distance and/or a speed of a target, a radar signal is transmitted in a direction of the target and a reflected radar echo is received, for which at least two transmission/reception channels are used whose signal paths each include an antenna and a mixer; at least one mixture is switched over from a first into a second operating state, in order to use the mixer, in the first operating state, bidirectionally as a transfer mixture, and, in the second operating state, in an at least approximately isolating manner as a receiving mixer.

Multibeam radar sensor apparatus and method for determining a distance

A radar sensor having a transmission module and a signal stabilizer, which are situated on a shared circuit board, a casing, which accommodates the signal stabilizer and forms a shield against high frequency radiation of the signal stabilizer together with a conductive layer of the circuit board, and having a connection line, which crosses through the shield, to connect the signal stabilizer to the transmission module, in which the connection line is embedded in the circuit board in insulated fashion.

Radar sensor having a shielded signal stabilizer

A monostatic multi-beam radar sensor for motor vehicles, having a group antenna, a planar lens having multiple inputs, and a homodyne mixer system, wherein the mixer system comprises multiple transfer mixers that are connected in parallel to the inputs of the lens.

Monostatic planar multi-beam radar sensor

In a device for measuring angular positions by using radar pulses and mutually overlapping beam characteristics of at least two antenna elements, a switchable phase shifter is provided in the signal path of at least one antenna element which is switchable in the time-division multiplexing between different phase states. For the radar received signals, an evaluation device is provided for the joint and especially simultaneous evaluation of signals of two antenna elements with the participation of antenna element, in whose signal path a switchable phase shifter is provided.
