摘要：
A numerical simulation about multi-turn uniform circular antenna arrays(UCAs) at the transmitter while single-turn UCAs at the receiver (MUSU) is proposed. It is assumed that each antenna element is isotropic without coupling, The wavefront phase diagram of the irradiated orbital angular momentum (OAM) beam and the total channel capacity of the model is calculated. The results show that increasing the number of UCAs at transmitter can improve the helical wavefront of OAM beam, in the case of a certain transmitting power, the OAM communication capacity can be improved.
