摘要
高的通信速率必然会占用更多的频带宽度,针对目前无线通信信道容量需求与频谱资源短缺的问题,结合轨道角动量这一新的频谱复用资源与相控阵馈电技术,设计了一种可以工作于Ku波段的涡旋电磁波圆环阵列天线.将8个结构相同的单元天线等间隔分布在一个同心圆面上,单元天线采用一种新型的圆环贴片,相邻馈电元件之间保持恒定相位延迟从而产生不同模式的OAM射电波束.仿真实验结果表明:天线回波损耗-10dB工作带宽为2.51GHz(14.15~16.66GHz)且生成了7种不同OAM模态的涡旋电磁波束.
In view of the problem of wireless communication channel capacity demand and spectrum resource shortage,combined with Orbital Angular Momentum(OAM),a new spectrum reuse resource and phase array feed technology,a vortex electromagnetic wave loop array antenna designed to operate in the Ku band is designed.The 8 cell antennas with the same structure are equally spaced on a concentric circular surface.The cell antenna adopts a new type of ring patch,which keeps the constant phase delay between the adjacent feed elements and generate different modes of OAM radio beam.The simulation results show that the antenna echo loss-10 dB working bandwidth is 2.51 GHz(14.15~16.66 GHz)and seven different OAM modes of vortex electromagnetic beam are generated.
