Title:
ANALOG BEAMFORMING ANTENNA ARRAY HAVING LOW COMPLEXITY
Document Type and Number:
WIPO Patent Application WO/2019/148512
Kind Code:
A1
Abstract:
Disclosed in the present invention is an analog beamforming antenna array having low complexity, relating to the technical field of communications. Said array comprises one or more sub-arrays having an independent analog beamforming function, each sub-array comprising a metal reflector plate, an antenna radiation unit array and a digital phase shifter; the digital phase shifter is directly connected to a radiation unit or a unit group, at least one digital phase shifter has different numbers of bits or has different total delay measuring ranges, and by reducing the amounts of phase shifts of some of the phase shifters, the complexity thereof can be reduced. By means of the combined use of the digital phase shifters having different numbers of bits or having different total delay measuring ranges, the analog beamforming scheme according to the embodiments of the present invention reduces the complexity of a Massive MIMO antenna array, reducing the power consumption and the cost, providing an economical and more practical solution for large-scale deployment of a 5G mobile communication system.
