为解决目前轨道角动量(OAM)天线难以在同一频率下多模工作的问题,推动OAM在无线通信领域的实际应用,设计、加工并测量了一种基于单层板的谐振环形行波天线,引入4 个馈电探针将不同相位差的信号馈入行波天线.经仿真分析和实际测量,该天线可以在 3 GHz上谐振并分别产生了携带有OAM模式l =0,l =±1,l =-2 的涡旋电磁波束.该天线结构简单并且可以在同一频率下产生多种模式OAM,能够有效增加无线通信的信道容量,具有一定的理论意义和实用价值.
Resonant ring shaped traveling wave antenna design for multi-mode OAM
Aiming at the problem that current orbital angular momentum(OAM)antennas is difficult to work in multi-mode at the same frequency and promote the practical application of OAM in wireless communication,a resonant-ring-shaped traveling wave antenna based on a single-layer substrate is designed,fabricated and measured,and four feed probes are introduced to feed signals with different phase differences into the traveling wave antenna.After simulation analysis and actual measurement,the proposed antenna successfully resonates and vortex electromagnetic beams are generated carrying OAM modes with l =0,l =±1and l =-2 at 3 GHz,respectively.The antenna has a simple structure and can generate multiple modes of OAM at the same frequency,which can effectively increase the channel capacity of wireless communication and has certain theoretical significance and practical value.
