While 6G standards are some way off, there is much useful work to be done extrapolating from current trends and progressions in 5G, along with the parallel evolution of technologies such as AR, AI and ML
Energy consumption is an important point which is crucial for green communications in 6G era, especially for those networks with limited life span or affected by dangerous environments where batteries are inconvenient to be changed. Therefore, energy harvesting (EH) has become a very attractive research field in recent years. In this paper, a new type of two-way EH relay beamforming system with two transceivers and many single-antenna relays is designed.
This work reviews several key
research trends in antennas to fulfil demands for the fifth
generation of communications (5G) and beyond, especially 6G,
and considers novel antenna techniques and designs needed to
increase the smartness of the antenna systems and to provide
improved beamforming and security.
