近年来，利用无线电波的轨道角动量（OAM）的通信引起了人们的广泛关注。设计了一种新型的毫米波双OAM模式天线，并利用该天线实现了60 GHz的双OAM信道无线通信链路。双OAM天线的主体是一个行波环形谐振器，使用由90°混合耦合器馈电的两个馈电端口。抛物面反射器用来聚焦光束。所有天线组件均通过3D打印技术和化学镀铜表面处理工艺制造。测量了天线的S参数、近场、方向性和两种OAM模式之间的隔离度等性能。实验结果表明，该天线可以同时辐射两个同轴传播的OAM模波束。在天线本身中容易实现复用和解复用。两个OAM模式通道具有20 dB以上的良好隔离度，从而同时保证了可靠的传输链路。
Communications using the orbital angular momentum (OAM) of radio waves have attracted much attention in recent years. In this paper, a novel millimeter-wave dual OAM mode antenna is cleverly designed, using which a 60 GHz wireless communication link with two separate OAM channels is experimentally demonstrated. The main body of the dual OAM antenna is a traveling-wave ring resonator using two feeding ports fed by a 90° hybrid coupler. A parabolic reflector is used to focus the beams. All the antenna components are fabricated by 3D printing technique and the electro-less copper plating surface treatment process. The performances of the antenna, such as S-parameters, near-fields, directivity, and isolation between the two OAM modes are measured. Experimental results show that this antenna can radiate two coaxially propagating OAM modes beams simultaneously. The multiplexing and de-multiplexing are easily realized in the antennas themselves. The two OAM mode channels have good isolation of more than 20 dB, thus ensuring the reliable transmission links at the same time.
