An antenna array, especially for spacing ascertainment or speed ascertainment in the surroundings of motor vehicles, includes devices for transmitting and/or receiving signal waves, which includes a shielding layer construction, made up of at least two layers, which includes the transmitting or receiving devices at least in part. To achieve above all a good immunity to interference, the antenna array includes a differential input buried in a dielectric layer and it includes a transmitting and/or receiving dipole, which is composed of two separate dipole halves.
