Patent ID: 8462047

Claim:
An antenna, comprising a beamforming network and multiple antenna arrays; wherein: the beamforming network comprises a hybrid network and a power dividing apparatus; the hybrid network comprises a base station signal port that communicates with a base station transceiver, and the hybrid network is configured to perform phase adjustment for signals sent by the base station transceiver and received through the base station signal port, generate signals having a preset phase, and send the signals to the power dividing apparatus; the power dividing apparatus comprises multiple antenna signal ports configured to communicate with the antenna arrays, wherein each antenna signal port is connected to one antenna array; and is configured to perform amplitude adjustment for the signals received from the hybrid network, and output multipath signals having an array amplitude and the preset phase to the multiple antenna arrays; and the multiple antenna arrays are configured to transmit the multipath signals received from the power dividing apparatus, wherein the transmitted multipath signals have an array phase and the array amplitude; and in the received multipath signals, one of the following condition is met: the preset phase of each path of signals is the same as the array phase of the signals when the signals are transmitted, and the preset phase of at least one path of signals is opposite to the array phase of the signals when the signals are transmitted.
