| 摘 要： | 针对圆环形阵列天线产生轨道角动量(orbital angular momentum,OAM)涡旋电磁波的技术,提出了一种基于多层板设计的双环形径向均匀圆阵列天线,用于产生多种OAM模式。以L型探针馈电的圆微带天线为单元,将多个相同的单元天线等间隔的分布在一个同心圆上组成双环形阵列天线,并采用等幅且同一圆环的相邻阵元间以连续相位差的方式馈电。HFSS仿真表明,上述天线阵可以产生具有多模式轨道角动量的涡旋电磁波束。所提出的天线可作为利用OAM进行相位分集的候选天线以增加无线通信的信道容量。

| Abstract: | A dual-ring radial uniform circular array antenna is proposed in this paper for multi-mode orbital an-gular momentum generation based on a multilayer substrate design.A circular microstrip antenna fed by an L-shaped probe was used as a unit,and a plurality of identical unit antennas were equally spaced on a concentric circle to form a double-ring array antenna,which can generate multiple OAM modes by using unit amplitude and continuously fixed phase difference between array elements in the same ring.Experiment results show that the array antenna can generate vortex electromagnetic beams with characteristic of multi-mode orbital angular momentum.The proposed antenna can serve as a candidate for utilizing OAM diversity,namely phase diversity to increase channel capacity of wireless com-munication. |
