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.

Abstract: Embodiments of the present invention relate to an antenna array, an antenna apparatus, and a base station. The antenna array includes: at least two antenna sub-arrays, where the at least two antenna sub-arrays are arranged in a vertical direction, each of the antenna sub-arrays includes multiple radiating elements, and in at least two adjacent antenna sub-arrays in the vertical direction, radiating elements at corresponding positions in the respective antenna sub-arrays are arranged in a staggered manner in a horizontal direction. In the embodiments of the present invention, horizontal side lobes and vertical far side lobes in an antenna array pattern are reduced, and the ultra-wideband performance is improved.
