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.

Antenna device

A failure compensation method includes detecting a Digital Beam-forming (DBF) coefficient of each of multiple transceiver channels in real time. When a failure of any one of the transceiver channels is detected, a current group of DBF coefficients of the multiple transceiver channels at a current failure status and corresponding failure mode information are obtained. Optimization processing is performed on the current group of DBF coefficients through a preset optimization algorithm so as to calculate a first group of DBF coefficients which is more adaptive to the failure mode information than the current group of DBF coefficients. The DBF coefficients of the transceiver channels are updated according to the first group of DBF coefficients.

Failure compensation method and apparatus for an active antenna, and active antenna device

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 connected to a radio remote unit (RRU) or a macro base station through a feeder. 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 optical fiber interface connected to the BPU. The optical fiber interface is connected to a baseband unit (BBU) through an optical fiber. Therefore, after the existing passive antenna is replaced by the provided antenna device, the RRU or macro base station in the original network can still be used, which reduces waste of resources.
