Integrated circuit for distance and / or speed measurement of objects

An integrated circuit (100) for distance and / or speed measurement of objects comprising: a high-frequency signal generating means (10, 11) for generating a first RF signal (13) having a predetermined frequency and a predetermined modulation history of at least one low-frequency signal (12); a mixing device (14) which is coupled to the high-frequency signal generating means (10, 11) for determining a frequency offset (18) between the first RF signal (13) and a reflected second RF signal (17); a transmitting / receiving means (16; 116) which is coupled to the mixing means (14) for transmitting the first RF signal (13) and simultaneously receiving the reflected second RF signal (17), which is dependent on the predetermined modulation profile of the the first RF signal (13) and a distance to a reflecting object is; and a matching device (15) interposed between the mixing device (14) and the transmitting / receiving means (16; 116) is coupled to adjust the impedance of the transmitting / receiving device (16; 116) in dependence on the frequency of the first RF signal (13); wherein the transmitting / receiving device (16; 116) is a patch antenna in a predetermined orientation, particularly in a 0 ° or 45 ° angle of a broad side of the patch antenna to a longitudinal side of the integrated circuit, preferably for a frequency range of the first RF signal between 30 GHz and 300 GHz has.
