abstract = "This paper mainly designs an antenna feed system based on vortex waves at 2.4GHz, and uses linearly polarized circular antenna arrays to generate vortex waves. Multimodal simultaneous transmission is possible by feeding the array with a butler matrix. After that, the system is tested, and the results show that its modal isolation meets the design requirements, and it can be used as a new multiplexing method to realize the transmission of four-channel signals without interfering with each other in space.",
