摘要
当前,5G已经在通信领域成为一个新兴的热门话题。虽然它能够大大提高人们的交互效率,但依然无法解决信号相对闭塞地区的交互质量低问题,如地铁站、地下商场等场所。而频段在13.56 MHz的近场交互式技术能够提高便携式设备通信与能量传输的效率,很好地弥补了5G的这一缺陷。根据IEEE国际标准ISO14443A/B,讨论近场交互线圈天线匹配电路的设计研究,针对两种结构不同的线圈天线分别设计并联和串联匹配电路。仿真结果显示,两种匹配电路都能够优化线圈天线的匹配特性。
Currently, 5G becomes an emerging hot topic in the field of communications. Although it can greatly improve people's interaction efficiency, it still cannot solve the problem of low interaction quality in signal-blocked areas, such as subway stations and underground shopping malls. The near-field interactive technology with a frequency band of 13.56 MHz can improve the efficiency of communication and energy transmission of portable devices, fairly making up for this defect of 5G. According to the IEEE International Standard ISO14443A/B, the design research of the near-field interactive coil antenna matching circuit is discussed. Parallel and series matching circuits are designed for the two coil antennas with different structures. Simulation results indicate that the two matching circuits can optimize the matching characteristics of the coil antenna.
