Abstract: Printed circuit boards suitable for base station antennas have a first through hole for receiving a conductor of an electrical connector and a first conductive trace for electrical connection with the conductor to transmit signals. The first conductive trace is provided on a first side of the printed circuit board and the electrical connector is located on the same side of the first conductive trace when mounted on the printed circuit board. The conductor is electrically connected to the first conductive trace via a bypass provided on a second side of the printed circuit board, opposite to the first side. The printed circuit board can be provided for a base station antenna that includes a calibration board including the printed circuit board. The printed circuit board can facilitate the good positioning of the electrical connector thereon, the good electrical performances, or can avoid a possible short circuit.
