摘　　要：为了达到提升通信容量和频率效率的目的,提出了一种基于环形槽线结构的OAM天线,并设计了由威尔金森功分器和90°相移器组成的馈电网络,使天线以双端口正交信号馈电的方式激励。分析了当OAM模式不同时,天线的工作特点;考察了馈电网络对天线性能的影响;模拟了OAM波束在收发天线之间的传播场景。结果表明,基于环形槽线结构的天线可有效生成高质量的多种模式OAM波束。In this paper, an OAM antenna based on annular groove structure is proposed, and a feed network composed ofWilkinson power divider and 90 degree phase shifter is designed. The antenna is excited by double-port quadrature signal feeding. The operation characteristics of the antenna are analyzed when the OAM mode is different,and the influence of feed network on the antenna performance is investigated. Furthermore,the propagation scene of the OAM beam between the transmitting and receiving antennas is also simulated. The results show that the presented antenna can effectively generate multi-mode OAM beam with high quality.
