Disclosed is an antenna system. The antenna system comprises: an antenna module, used for receiving and/or transmitting at least one first radio frequency signal and receiving and/or transmitting at least one second radio frequency signal; and a power-division phase-shift network module, used for controlling an amplitude and a phase of each radio frequency signal in the antenna module, control parameters for controlling the phase and the amplitude of each of the first radio frequency signals being configured according to a beam pointing direction and a beam width required by a three-dimensional construction region and control parameters for controlling the amplitude and the phase of each of the second radio frequency signals being configured according to a beam pointing direction and a beam width required by a ground region. In this manner, the problems in the prior art are solved that the difficulty in maintaining antennas is great, the difficulty in obtaining sites of the antennas is great and costs are high due to arrangement of many antennas. |
