| 摘 要： | 轨道角动量(OAM)复用传输是一种新兴的无线电传输技术。利用单馈电点环形微带矩形贴片天线的辐射特性来产生C波段OAM的螺旋波束,并制作出环形OAM阵列天线。为验证OAM阵列天线的传输性能,将OAM天线与通用软件无线电外设(USRP)相结合,利用软件无线电(SDR)技术搭建一个OAM无线传输系统。经实验证明该系统可在真实的信道环境中实现音频信号的实时传输。鉴于OAM复用传输技术具有传输安全性好、频谱利用率高的优势,OAM系统的搭建在无线通信中具有一定实际意义,在未来通信领域具有潜在应用价值。

| Abstract: | The multiplex transmission of orbital angular momentum (OAM) is a new radio transmission technology. In this paper, the radiation characteristics of a single-feed point annular microstrip rectangular patch antenna are used to generate a C-band OAM helical beam, and a ring OAM array antenna is fabricated. To verify the transmission performance of the OAM array antenna, the OAM antenna is combined with the Universal Software Radio Peripheral (USRP) to build an OAM wireless transmission system using Software Defined Radio (SDR) technology. The experimental results show that the system can realize real-time transmission of audio signals in real channel environment. Because the OAM multiplexing transmission technology has the advantages of good transmission security and high spectrum utilization rate, so the construction of OAM system has certain practical significance in wireless communication, and it has potential application in the future communication field. |
