Due to the high loss of propagation in millimeter wave (mmwave) and terahertz band (THz) used in fifth generation and Sixth generation telecommunication systems, the cells become much dense and more compact. On the other hand, because of the growing in the user’s demand on more bandwidth, employment of the beamforming techniques with Massive Multi-input Multi-output (Massive MIMO) are very important in order to increase spectral efficiency, proper and cost-effective coverage. Holographic beamforming technology is one of the latest techniques in the beamforming that has many advantages over the old these kinds of techniques such as Analog Beamforming and Digital Beamforming. Therefore, for taking the advantage of the next generation of telecommunication networks, it is necessary to be aware of the different sections of technologies like the antennas, and along with these technologies, entered into the equipment market of these growing technologies, also. In this research, some of the latest techniques and methods of beamforming are investigated and compared with each other. At the end, a suitable method is proposed according to the requierements of next telecommunication networks and technological trends.
