摘　　要：近场通信是基于无线射频技术发展起来的一种近距离无线通信技术。针对目前无法满足移动终端大容量、高效率的数据传输要求的问题,主要通过近场耦合的方式实现高速通信的方法,本文建立了天线耦合器近场特性分析的FDTD计算模型。采用调制高斯脉冲馈电,通过FDTD方法进行仿真,详细分析了在不同位置坐标处的时域波形和对应频谱,同时将不同形状的电磁耦合器进行比较从而得到最优化模型。这一研究结论对高速近场通信天线的设计具有一定的参考价值。Near field communication is a kind of short distance wireless communication technology based on the development of the wireless radio frequency technology.In view of the present can not meet the requirements of data transmission in a mobile terminal of large capacity,high efficiency of the problem,in this paper,the main methods to realize high speed communication is presented in this paper.The analysis of near field characteristics of antenna coupler FDTD computing model bynear field coupling way.The modulation of Gauss pulse feed,by FDTD simulation method,analyzed in detail for different position coordinate corresponding time-domain waveform andspectrum,electromagnetic coupler and at the same time shape compared so as to obtain the optimization model.It has certain reference value to the conclusions of the study design of high-speed near-field communication antenna.
