Abstract
The present invention relates to 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 is configured to be connected to RF circuitry, and the at least one antenna element is embedded in the PCB. The present invention also relates to an antenna arrangement and a communication device for wireless communication comprising a PCB with at least one embedded antenna element.
