3D coverage optimization research on 5G massive MIMO antenna array

This paper analyzed the structure of 5G(5th generation mobile system) massive MIMO antenna array, and presented a 3D(three dimension) coverage optimization method. Integrating and optimizing two main plane patterns of the target 3D radiation pattern, the overall 3D beamforming and coverage optimization of the array are realized. In addition, the 3D beamforming optimization method is tested and verified by simulation, which prove the efficiency of optimization method.
