摘要： 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.

摘要： An apparatus includes a plurality of sensor modules that are disposed at spacings with respect to one another, each sensor module having a local oscillator device. The oscillator device generates an oscillator signal that is passed on to a transmit/receive device, and the oscillator signal is radiated. The transmit/receive device is set up such that it can receive signals reflected from the object. A phase detection device is coupled at one input to the oscillator device and at a second input to the transmit/receive device. Based on the oscillator signal and the received reflected signals, the phase detection device determines a phase signal. A control and signal-processing device determines, based on the spacings of the sensor modules with respect to one another and the phase signals, a direction of the object with respect to the sensor module.

摘要： 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.
