Claim:
1. A printed-circuit board arrangement comprising: a printed-circuit board including a first metal layer, a second metal layer, and a third metal layer, the second metal layer being arranged below the third metal layer and arranged above the first metal layer, an amplifier unit; and at least two slot antennas formed respectively by apertures in the second metallic layer and coupled to the amplifier unit via a three-line system, wherein the three-line system includes three strip lines mounted on the printed-circuit board or introduced into the printed-circuit board extending parallel to one another, wherein voltages, which differ in modulus and phase, are guided along a first strip line and a second strip line of the three-line system, wherein a third strip line of the three-line system serves as a common ground line for the first strip line and the second strip line, wherein a first patch is embodied in the third metal layer, the first patch being excited from the three-line system, and wherein the apertures continue from the at least two slot antennas in a direction towards the amplifier unit and separate the three strip lines extending parallel to one another.
