[Abstract]:The rapid development of wireless communication technology has greatly improved people's working efficiency and quality of life, but also for the continuous development of the information society to provide a huge power. Space-division multiplexing (STDM) technology has received great attention and development, because it can double the transmission rate of the system without using additional spectrum resources, as a special form of space-division multiplexing. Vortex electromagnetic wave communication based on carrying orbital angular momentum (OAM) provides a spiral dimension, which greatly improves the spectral efficiency of the communication system. It is gradually becoming a research hotspot in electromagnetic field and communication field. In this paper, the following three aspects of the RF vortex electromagnetic wave communication work are done: first, to solve the problem of RF vortex mode multiplexing. A four OAM mode multiplexing antenna based on stacked ring traveling wave slot resonator is designed. The frequency of the antenna is 10 GHz. The performance of the antenna is measured experimentally. Secondly, using a pair of processed antennas, a radio frequency radio frequency communication system based on four OAM mode antennas is built, and the wireless transmission capacity close to Gbit/s is realized. The communication distance is 10 meters. The experimental results show that the RF electromagnetic vortex communication can greatly reduce the receiving complexity of the system without sacrificing the communication capacity. Thirdly, in order to solve the problem that the aperture of receiving antenna is too large due to the increase of transmission distance, a compact receiving scheme based on optimized OAM mode selection is proposed. The feasibility of this method is proved by theory, simulation and experiment. In this paper, the radio-frequency vortex electromagnetic communication system transmitter, wireless link. And the receiving end of the detailed theoretical and experimental research, analysis of the electromagnetic vortex communication problems and put forward some feasible solutions to promote the development of radio frequency electromagnetic vortex wireless communication. Finally. The future of RF vortex electromagnetic communication is prospected.
