为了探索一种新的产生轨道角动量（Orbital Angular Momentum,OAM）的方法，根据圆形阵列天线理论，提出了一种基于旋转单元法的极化OAM透射阵，能够形成旋转电磁场，进而产生极化正交的OAM波。该极化OAM波透射阵分为中间的地层和上下2层贴片，总共由14个透射单元组成，外圈包含9个单元，内圈包含5个单元，均匀轴向排布在一个同心圆上。该透射阵通过单元的旋转使电磁波产生极化旋转的特性，从而可以在空间中通过调控电场的极化来实现信号正交，以提高信道容量。仿真和测试结果均表明，该极化OAM波透射阵工作于10 GHz，在透射阵口面存在极化OAM特性，且透射阵的最大增益为5.5 dBi。因此，探索极化OAM波为无线通信提供了一种新的可能。
Abstract：In order to explore a new method of generating Orbital Angular Momentum(OAM),a polarized OAM wave transmission array based on rotating element method is proposed according to the principle of uniform circular array antenna,which can form a rotating electromagnetic field and then generate the polarized orthogonal OAM wave. The proposed polarized OAM wave transmission array is divided into an intermediate layer and an upper and lower layer patch,which consists of 14 transmission elements,with the outer ring containing 9 elements and the inner ring containing 5 elements,evenly spaced axially over a concentric circle. The transmission array makes the electromagnetic wave produce the characteristic of polarization rotation through rotating element,so that the polarization of the electric field can be adjusted in space to realize signal orthogonality,so as to improve channel capacity.Simulation and test results show that the polarization OAM transmission array which operates at 10 GHz has polarization OAM characteristics at the aperture of the transmission array,and the maximum gain of the transmission array is 5. 5 dBi. Therefore,exploring polarized OAM waves provides a new possibility for wireless communication.
