Abstract: Orbital Angular Momentum (OAM) vortex electromagnetic waves are mostly generated by complex systems.In order to obtain OAM electromagnetic waves easily,a circularly polarized nut-shaped antenna is designed.By controlling the relative positions of two feeding points,a specific mode of circularly polarized vortex electromagnetic waves with OAM is generated.The theoretical deduction and simulation results prove the effectiveness of the nut-shaped patch antenna.Compared with the traditional shaped patch antenna,the proposed antenna is smaller and more compact,with improved spatial radiation phase distribution and resonance characteristics.

Key words: Orbital Angular Momentum(OAM), vortex electromagnetic wave, helical phase distribution, quantum communication, nut-shaped patch antenna

摘要: 轨道角动量(OAM)涡旋电磁波大多通过复杂的系统生成,为简易地获取OAM电磁波,设计一种圆极化螺母型贴片天线。通过控制2个馈电点的相对位置,生成特定模式的OAM圆极化涡旋电磁波。理论推导和模拟仿真结果证明了该螺母型贴片天线的有效性。与传统形状的贴片天线相比,该天线结构小巧紧凑,改善了空间辐射相位分布与谐振特性。
