Abstract
This disclosure provides an antenna system to improve communication flexibility. The antenna system includes a radio frequency unit, a divider, a first modulator, a second modulator, a first antenna and a second antenna. The radio frequency unit is configured to generate a first radio frequency signal. The divider is configured to divide the first radio frequency signal into first and second radio frequency sub-signals. The first modulator is configured to adjust a first electrical downtilt of the first radio frequency sub-signal and send the adjusted first radio frequency sub-signal to the first antenna for transmission. The second modulator is configured to adjust a second electrical downtilt of the second radio frequency sub-signal and send the adjusted second readio frequency sub-sibnal to the second antenna for transmission. The adjustion is based on a target downtilt of the first radio frequency signal and a mechanical downtitlt of the first or second antenna.
