用于产生OAM涡旋光束的圆极化正八边环形贴片天线
|
摘要
针对目前已有的轨道角动量(OAM)的生成方法的不足,设计了一种能够产生多个OAM拓扑荷的圆极化正八边环形贴片天线,对该天线的回波损耗、二维增益方向、三维增益方向和空间辐射相位分布等性能指标进行了仿真研究,仿真结果表明各项性能指标符合要求。
In view of the shortcomings of the existing methods for generating orbital angular momentum(OAM), this paper proposes an circularly polarized regular octagon ring patch antenna that can generate multiple OAM topological charges. The performance indexes such as return loss, two-dimensional radiation pattern, three-dimensional radiation pattern and spatial radiation phase distribution of the antenna are simulated and studied. The simulation results show that the performance indexes meet the requirements.
