Abstract The millimeter-wave multiple input multiple output (MIMO) technology is the frontier for 5G communication systems. This work contributes a large antenna array with a limited number of radio frequency chains using the hybrid beamforming (HBF) technique that overcomes extreme path loss in the mmWave system to improve spectral efficiency. The link budget analysis is given for the target data rate of 11.3 Gbps for the point-to-point communication. The number of antenna elements required for the proposed antenna array is determined via link budget analysis. The proposed system includes single element patch antenna configuration, array factor analysis, and beam steering capability. The transmit and receive antenna gain specifications minimize the path loss and improve the system throughput. Combiners and hybrid precoders are designed together in an iterative way for reducing the cost function of the weighted minimum mean squared(WMMSE) error. Simulation results demonstrate that the proposed HBF algorithm performance is highly effective and performs closer to the fully digital beamforming technique. The proposed large antenna array with HBF uses the New York University Simulator (NYUSIM) to perform omnidirectional and directional power delay profile analysis with the most potent power. The proposed large antenna array with HBF methodology provides an optimal approach to indoor point-to-point communication deployments.
