A radar arrangement includes a printed circuit board (PCB), an electronic component, and an antenna. The electronic component is arranged on the PCB and is used to generate a high-frequency signal. The PCB has at least four electrically conductive layers separated from one another by at least three electrically insulating layers. A first conductive inner layer is adjacent to a first conductive outer layer, and a second conductive inner layer is adjacent to a second conductive outer layer. The electronic component is arranged on the first conductive outer layer. The antenna is formed at least partially in the second outer layer. The signal generated by the electronic component is transmitted to the antenna, which is formed at least partially in the second conductive outer layer of the PCB, through a region of the conductive inner layers and insulating inner layers of the PCB.

Radar arrangement

A radar antenna arrangement includes a plurality of transmitting elements and with a plurality of receiving elements. The transmitting elements are arranged in a transmitting arrangement and the receiving elements are arranged in a receiving arrangement, in each case in fields of a regularly hexagonally parqueted surface. An associated virtual antenna arrangement of virtual antenna elements results from the geometrical convolution of the transmitting arrangement with the receiving arrangement. High angular resolution and good alignability with good directional independence can be achieved by arranging the receiving elements in the receiving arrangement and the transmitting elements in the transmitting arrangement so that the virtual antenna elements in the virtual antenna arrangement are arranged without overlap.
