Base station antenna and base station

Abstract

Embodiments of this application provide a base station antenna and a base station. The base station antenna includes a first antenna array, a metasurface lens, and a second antenna array. The metasurface lens is located between a first radiator of a radiating element of the first antenna array and the second antenna array. The metasurface lens is configured to: reflect a radiation signal of the first antenna array, and perform wavefront phase modulation and transmission on a radiation signal of the second antenna array, so that the radiation signal of the second antenna array that passes through the metasurface lens is approximately focused into a plane wave. The base station includes the base station antenna.
