Abstract: Embodiments of the present invention relate to the field of communications technologies, and provide a base station antenna and a base station antenna feed network. The base station antenna includes a transceiver array, a first-level vector synthesis network, a second-level phase shifter array, a second-level vector synthesis network, and an antenna unit array. By using the second-level vector synthesis network, the base station antenna makes phase differences between multiple vector signals sent to antenna units smoother, thereby extending an adjustable range of a downtilt on the premise that the number of transceivers is as small as possible.
