Embodiment Construction

[0014] exist figure 1 A partial area of ​​a circuit board 10 suitable for high frequencies is shown in , on which a circuit pattern consisting of microstrip lines forming a high frequency circuit is formed. In the example shown, the circuit board 10 is a circuit board of a resonator on which four antenna patches 12 are arranged, which are used to emit radar signals.

[0015] The radio-frequency circuit serves to feed two different radio-frequency signals (radar signals) TA and TB into the radar patch 12 . In this case, the antenna patches 12 form two interleaved groups A and B which are respectively intended to emit one of the two radio-frequency signals TA and TB. Correspondingly, the high-frequency circuit forms a first line 14 and a second line 16, the first line is used to supply the high-frequency signal TA to the antenna patches of the group A, and the second line is used to supply the high-frequency signal TA TB provides antenna patches for group B. The line 14 has a...

Abstract

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.

Description

technical field [0001] The invention relates to a high-frequency circuit having lines for high-frequency signals arranged crosswise on a circuit board. Background technique [0002] Such high-frequency circuits are used in radar technology—for example, radar sensors, which are used in motor vehicles to measure the distance and relative speed of preceding vehicles in order to enable automatic collision warning or distance regulation. [0003] Typically, the high-frequency circuit then comprises a plurality of feed lines which connect a plurality of antenna patches arranged on the same printed circuit board to the associated oscillator and evaluation circuit. In order to achieve a defined angular distribution of the emitted radiation for a transmitting antenna, it is often desirable to feed groups of crosslinked or alternately arranged antenna elements with signals that differ in their phase, amplitude and / or frequency. If the antenna patches are only formed in two groups, it...
