ANTENNA SYSTEM

摘要

Embodiments of the present invention provide an antenna system, comprising: a TRX array module, an antenna oscillator array module, a feed network module, and a Butler matrix module. The TRX array module comprises a plurality of active TRX sub-modules and is configured to generate a transmission signal subject to digital beam forming. The antenna oscillator array module comprises a plurality of antenna oscillators and is configured to transmit the transmission signal. The feed network module is configured to form a vertical beam characteristic of the antenna oscillator array module before the antenna oscillator array module transmits the transmission signal. The Butler matrix module is configured to form a horizontal beam characteristic of the antenna oscillator array module before the antenna oscillator array module transmits the transmission signal. The antenna system provided by the technical solution uses an AAS antenna as a basic architecture. Compared with the conventional antenna, the antenna system reduces the feeder loss, saves the labor and device costs, enables the vertical and horizontal beam characteristics of the antenna to be adjusted more conveniently, and has a certain advantage on the spectrum resource utilization rate.
