1. A printed circuit board, PCB, with at least one integrated antenna element configured to transmit and/or receive radio frequency, RF, signals, each of the at least one antenna element being configured to be connected to RF circuitry, and the at least one antenna element being embedded in the PCB, the PCB comprising at least two antenna elements, which are electrically insulated from each other, and which are embedded in the PCB, the PCB being arranged in a plane, and a first antenna element and a second antenna element of the at least two antenna elements being arranged to at least partially overlap each other in a normal direction of the plane of the PCB, and a conductive pattern of the first antenna element being a mirror image of a conductive pattern of the second antenna element.
