摘　　要：轨道角动量(Orbital Angular Momentum,OAM)因其模数的无限性与正交性在提升通信容量方面有着巨大的潜力,对解决频谱资源不堪重负的现状有很强的现实意义,而OAM波束自身的发散角限制了其远距离通信的能力。OAM波束控制技术作为OAM波束固有的发散角问题的解决方案,极具研究价值和发展前景。介绍了近年来OAM波束控制技术的研究进展,包括抛物面天线法、透镜天线法、谐振腔法、超表面法以及其他波束控制技术。OAM波束控制技术尚不成熟,针对不同类型以及不同应用领域还需进行不同侧重的研究。With infinite and orthogonal modularity,orbital angular momentum(OAM)has great potential in enlarging the communication capacity,which has a strong significance in the practice of dealing with the overwhelmed spectrum resources.However,the divergence angle of OAM beam itself limits its application in long-distance communication.The technology of beam-steering of OAM antenna can be a solution to the inherent problem of divergence angle.The research progress of OAM antenna beam-steering technology is introduced,including parabolic antenna method,lens antenna method,resonant cavity method,metasurface method and other methods.Because the technology of beam-steering of OAM antenna is far from maturity,various researches on types and application fields should be done in the future.
