The present application provides an antenna control device, an antenna, and a base station. The antenna control device comprises a motor, a box body, an isolation assembly, and a transmission assembly; the motor comprises a motor body and a metal shaft, one end of the isolation assembly is sleeved at the end of the metal shaft distant from the motor body, the box body is provided with an opening penetrating the two opposite surfaces of the box body, the motor body and the metal shaft are located in the box body, the isolation assembly is arranged in the opening in a penetrating manner, the end of the isolation assembly distant from the metal shaft extends outside the box body, the transmission assembly is connected to the end of the isolation assembly distant from the metal shaft, and the end of the transmission assembly distant from the isolation assembly is connected to a sliding medium, so as to drive a phase shifter to operate. According to the present application, the isolation assembly is arranged in the opening in a penetrating manner, and is sleeved at the end of the metal shaft distant from the motor body, so that a motor signal is isolated in the box body, and the interference to an antenna signal is reduced.
