This paper proposes optimal beam patterns of analog beamforming for SU(Single User) massive MIMO (Multi-Input Multi-Output) transmission systems. Forhybrid beamforming in SU massive MIMO systems, there are several designparameters such as beam patterns, the number of beams (streams), the shape ofarray antennas, and so on. In conventional hybrid beamforming, rectangularpatch array antennas implemented on a planar surface with linear phase shiftbeam patterns have been used widely. However, it remains unclear whetherexisting configurations are optimal or not. Therefore, we propose a methodusing OBPB (Optimal Beam Projection Beamforming) for designing configurationparameters of the hybrid beamforming. By using the method, the optimal beampatterns are derived first, and are projected on the assumed surface tocalculate the achievable number of streams and the resulting channel capacity.The results indicate OBPB with a spherical surface yields at least 3.5 timeshigher channel capacity than conventional configurations.
