Abstract: An antenna system with a beam with an adjustable tilt, including: a transceiver (TRX) array module, an antenna element array module, a feeding network module and a Butler matrix module, is provided. The TRX array module includes multiple active TRX submodules and is configured to generate transmission signals that have undergone digital beam forming. The antenna element array module includes multiple antenna elements and is configured to transmit the transmission signals. The feeding network module is configured to form a vertical beam characteristic of the antenna element array module before the antenna element array module transmits the transmission signals. The Butler matrix module is configured to form a horizontal beam characteristic of the antenna element array module before the antenna element array module transmits the transmission signals. The antenna system reduces the feeder loss, reduces the labor and equipment costs, and enables the vertical and horizontal beam characteristics of the antenna to be adjusted more conveniently.

Abstract: An antenna device is provided, which includes a first antenna unit and a second antenna unit. The first antenna unit includes a first radiation module, a power divider/combiner network connected to the first radiation module, and a feeder interface connected to the power divider/combiner network. The feeder interface is configured to connect to a radio remote unit (RRU) or a base station. The second antenna unit includes a second radiation module, a transceiver array connected to the second radiation module, a baseband processing unit (BPU) connected to the transceiver array, and an interface connected to the BPU. The interface of the second antenna unit is configured to connect to a baseband unit (BBU). Therefore, after the existing passive antenna is replaced by the provided antenna device, the RRU or base station in the original network can still be used, which reduces waste of resources.
