Abstract: This paper presents an orbital angular momentum (OAM) multiplexing communication system employing active uniform circular arrays (UCAs) to achieve simultaneous five-mode transmission. At 28 GHz, dual-loop UCAs are implemented in the transceiver, in which four UCAs comprising multiple 4×4 microstrip subarrays are placed concentrically. The next stage of each channel is an active transmitter and receiver (T/R) module, which is composed of a beamformer integrated circuit (IC) and a feed network. Additionally, a central antenna with the ability to transmit mode 0 is integrated. Similar to the active phased array system, both the receiving and transmitting modes are reconfigurable by adjusting the phase shifter. According to specific requirements, the modes of different UCAs can be assigned arbitrarily, and the receiving and transmitting states of each UCA can be configured independently. In this study, a 6-m OAM link with data transmission rate of 3 Gbit/s has been successfully implemented.

摘要：本文提出一种采用有源均匀圆阵列（UCAs）实现五模态同时传输的轨道角动量（OAM）复用通信系统。在28 GHz的中心频率下，设计了双环圆阵列收发阵面，每个阵面由多个4×4微带子阵列组成。每个模态采用独立的有源收发模块（T/R），其T/R由波束形成集成电路和馈电网络组成。装置中央额外集成了可以传输模态0的天线。与有源相控阵系统类似，装置能够通过调整移相器来重新配置接收和发射的模态。可以按照具体需求分配不同的OAM模式给各组UCA，且每个UCA的接收和发送状态可以独立配置。在本研究中，设计了一个距离为6米的OAM复用通信链路，实现了3 Gbit/s的数据传输速率。
