1. An antenna system, comprising:
a first antenna,
a second antenna,
a radio frequency unit configured to generate a first radio frequency signal;
a divider configured to divide the first radio frequency signal into a first radio frequency sub-signal and a second radio frequency sub-signal;
a first modulator configured to adjust a first electrical downtilt of the first radio frequency sub-signal and output the adjusted first radio frequency sub-signal to the first antenna for transmission, wherein the first electrical downtilt is adjusted based on a target downtilt and a first mechanical downtilt of the first antenna; and
a second modulator configured to adjust a second electrical downtilt of the second radio frequency sub-signal and output the adjusted second radio frequency sub-signal to the second antenna for transmission, wherein the second electrical downtilt is adjusted based on the target downtilt and a second mechanical downtilt of the second antenna, wherein the target downtilt is a same target downtilt of the first antenna and the second antenna.
