The present invention discloses an antenna system, where the antenna system includes an antenna module, configured to: receive and/or transmit at least one first radio frequency signal, and receive and/or transmit at least one second radio frequency signal; a power-split phase-shift network module, configured to control an amplitude and a phase of each radio frequency signal in the antenna module, where control parameters for controlling an amplitude and a phase of each first radio frequency signal are configured according to a beam pointing direction and a beam width that are required by a three-dimensional building region, and control parameters for controlling an amplitude and a phase of each second radio frequency signal are configured according to a beam pointing direction and a beam width that are required by a ground region. Therefore, a problem of relatively high costs and relatively big difficulty in obtaining an antenna site and maintaining an antenna caused by setting a great many antennas in the prior art is resolved. |
