摘要： 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.

摘要： The present invention relates to a board assembly used for a base station antenna and a base station antenna including such a board assembly. The board assembly includes a first circuit board (3) and a second circuit board (4), and the first circuit board and the second circuit board are spaced apart from each other. The first circuit board has a plurality of first electrical connectors, the second circuit board has a plurality of second electrical connectors, and the first electrical connectors and the second electrical connectors are electrically connected by a plurality of coaxial cable assemblies (5). Each coaxial cable assembly extends between the first circuit board and the second circuit board, and includes a coaxial cable, a first corresponding electrical connector matching the first electrical connector on a first end of the coaxial cable, and a second corresponding electrical connector matching the second electrical connector on a second end opposite to the first end on the coaxial cable. The board assembly can have stable electrical performance, especially radio frequency signal transmission performance.
