| Abstract: |
| One of the key technologies to break through the bottleneck of communication，the reconfigurable orbital angular momentum(OAM) antenna technology,for its advantages in line of sight(LOS) communication,can be widely used in data exchange of the data center,the air-to-ground communication of unmanned aerial vehicle(UAV),wireless backhaul communication and radar detection.This paper summarizes the current common mode,polarization,pattern and hybrid reconfigurable OAM antennas and their implementations.Then,it compares the performance of current reconfigurable OAM antennas.The future development of reconfigurable OAM antennas in the field of wireless communication is prospected,which provides reference for the research and optimization of the new reconfigurable OAM antenna.The research of reconfigurable OAM antenna is of great significance to the development of wireless communication systems.In the next step of reconfigurable OAM antenna development,it is necessary to combine new materials with metal structures,and a new type of the reconfigurable OAM antenna based on uniform circular array(UCA) principle is still the focus of research. |
