摘要
4G技术已经向5G过渡,6G等技术也在不断发展,无线通信以及航空航天等行业迫切需要具备波束控制能力更强、能适应变化场景、质量更轻体积更小的天线以实现高速通信、感知跟踪等功能。提出了一种可用于卫星通信和卫星遥感的透射超表面天线,该超表面天线由1 bit可重构单元构成,调节单元的相位状态能产生不同模态的涡旋波,并且能实现超过60°范围的不同模态涡旋波的波束扫描。结合涡旋波的特点,该设计可作为卫星通信遥感一体化等技术的天线结构,为通信及遥感卫星的设计提供了一种可重构、轻量化的新方案。
4G technology has been transiting to 5G,6G and other technologies are also under development,Wireless communication and aerospace industries urgently need antennas with stronger beam control ability,adapt to changing scenarios,of lighter weight and smaller volume to achieve high-speed communication,sensing and tracking functions,A transmission metasurface antenna for satellite communication and remote sensing is presented in this paper,The metasurface antenna is composed of a 1 bit reconfigurable element,The phase state of the modulating element can generate vortex waves of different modes,and can realize beam scanning of vortex waves of different modes in a range of more than 60°,Combined with the characteristics of vortex wave,the design can be used as the antenna structure of satellite communication remote sensing integration technology,providing a new reconfigurable and lightweight scheme.
