Claim 0:
1. A MIMO radar sensor for a motor vehicle, comprising:
an antenna assemblage on a rectangular circuit board whose edges define a y direction and a z direction;
wherein the antenna assemblage includes two arrays of transmitting antennas and two arrays of receiving antennas,
wherein transmitting antennas within each array of the two arrays of transmitting antennas being offset from one another in the z direction, and the two arrays of transmitting antennas are offset from one another in the y direction,
wherein receiving antennas within each array of the two receiving antennas being offset from one another in the y direction, and the two arrays of receiving antennas are offset from one another in the z direction,
wherein the two arrays of transmitting antennas are disposed adjacently to two mutually oppositely located edges of the circuit board,
wherein the two arrays of receiving antennas are disposed adjacently to two remaining ones of the edges of the circuit board, and
wherein at least one high-frequency module is disposed on the circuit board in a central region of the circuit board between the two arrays of transmitting antennas and the two arrays of receiving antennas, and
wherein the two arrays of transmitting antennas each include at least two transmitting antennas that are disposed at a same distance from a respective edge of the circuit board, and the two arrays of receiving antennas each include at least two receiving antennas that are disposed at a same distance from a respective edge of the circuit board.
