Abstract:

3D-Beamforming is a promising technique for mobile wireless communication systems to improve the system performance and realize green communications. By exploring the vertical dimension of the spatial area, 3D-Beamforming could enhance the signal to interference plus noise ratio of the received signal, raise the spectrum utilization rate and improve the energy efficiency. The fundamental theory of array antenna's 3D-Beamforming is studied. The half-power beam width (HPBW)of the beam at vertical dimension has been computed by Matlab simulation under influence of different factor. Simulation shows that horizontal angular does not affect the basic level of HPBW, with the increase of vertical angular, the HPBW increase significantly, but it can be decreased by adding more antenna array unit.

Key words: uniform planar array, 3d-beamforming, Matlab simulation
