用于太赫兹动态通信的多波束技术OA

With the continuous development of Radio Frequency(RF)devices,terahertz communication is evolving from point-to-point fixed communication experiments to communication applications in the moving state,and terahertz beam reconfigurable technology empowers multi-beam communication systems to provide support for terahertz dynamic communication.This paper introduces the research progress of phased array,meta-surface and other multibeam antennas in terahertz bands.The beam reconfiguration schemes and technical routes of terahertz dynamic communication are sorted out.The basic composition and key technologies of each scheme are analyzed.By discussing the advantages and disadvantages of each technical route,the development blueprint of terahertz dynamic communication system covering low frequency to high frequency is described.Multibeam technology will further accelerate the evolution of terahertz communication to flexible and changeable networking communication forms,and provide a technical foundation for the commercial application of 6G terahertz communication.
