Antenna Array Design for Higher Spectral Effeiciency for Hybrid Beamforming 5G MIMO Wireless Communication System

This paper presents the best suited antenna array for the hybrid beamforming in 5G MIMO wireless communication system. Investigation finds impact on the performance matric using different antenna array size. We design the transmitter antenna array of size 16×16, 8×8, 4×4, 2×2 for the 28 GHz frequency. Our intrigued of investigation and performance metric are spectral efficiency, energy efficiency and bit error rate. In this paper we shows, as the size of antenna array increase the spectral efficiency and energy efficiency will increase by great extent. We also find the bit error rate of wireless communication is reduced with the size of antenna array. Furthermore, we demonstrated our result using MATLAB as the larger size of antenna array increase beam is more steered in desired direction and reduced the side lobes in other direction.
