Radome and base station antenna

The utility model belongs to the technical field of communication, and provides an antenna housing and a base station antenna, the antenna housing comprises a lens array and an antenna housing substrate, the antenna housing is used for covering the antenna array, the antenna array comprises a plurality of antenna oscillators, the lens array comprises a plurality of lens units, and the lens units are arranged on the lens array. The antenna housing substrate is arranged on the side, away from the antenna array, of the lens array and connected with the lens array, and electromagnetic waves emitted by the antenna oscillator meet the formula that L = f + n (Lcos theta-f). According to the antenna housing provided by the utility model, the lens units and the antenna oscillators are arranged in one-to-one correspondence, so that the antenna oscillators can be located at the focal points of the corresponding lens units, and the wave path of electromagnetic waves emitted by the antenna oscillators propagating in the a
