摘要
涡旋电磁波不同轨道角动量(OAM)模态的正交性可以作为新的信息复用维度进一步提升系统通信容量。设计了一种基于双环圆形阵列的涡旋电磁天馈系统,可同时产生±1、±2四模态涡旋电磁信号。暗室测试及系统联试结果表明,设计的天馈系统模态间隔离度好,可完成4路同频BPSK数传信号的同时传输且无误码,实现了系统通信容量的提升。
The orthogonality of different orbital angular momentum(OAM)modes of vortex electromagnetic wave can be used as a new dimension of information muti-use freedom to further improve the communication capacity.A vortex electromagnetic antenna system based on double uniform circular array is designed,which can generate±1 and±2 four mode vortex electromagnetic signals at the same time.The results of anechoic chamber test and system test show that the designed antenna system has well isolation between different modes,completes the data transmission of four BPSK signals without error code,and achieves significant improvement of system communication capacity.
