摘　　要：石墨烯标签天线因具有价格低廉和环境友好的优势而有望替代金属标签天线。然而,石墨烯标签天线在制备过程中受到丝网印刷工艺和石墨烯油墨的影响,不可避免地引入不确定性,使得实际阅读距离与理论值不符。为指导包含不确定性的石墨烯标签天线的设计,使天线阅读距离处于特定范围内,提出一种基于区间分析的算法。通过分析天线理论公式,得到不确定性参数;根据制备经验,为每个不确定性参数估计区间范围,使用区间分析算法(包括区间数学建模和顶点法)计算阅读距离的上下限;通过实验测量了石墨烯标签天线的阅读距离,验证了所提算法。结果表明:所提算法可以有效地计算石墨烯标签天线的阅读距离区间,有助于石墨烯标签天线的实际使用,并为制造过程中的不确定性分析提供指导。Graphene tag antenna,owing to its low price and environmental friendliness,is a promising alternative to metal tag antenna.However,graphene antennas inevitably suffer from property uncertainties due to the manufacturing process of screen printing and the properties of graphene inks,making their real read range different from the theoretical one.A unique interval-based computation algorithm is proposed to guide the design of graphene antennas with uncertainties considered,as well as to make the read range particular.Firstly,uncertainty parameters are obtained by analyzing the theoretical formulas of antennas.Second,using an interval analysis approach that includes the interval mathematical modeling and the vertex algorithm,the upper and lower bounds of the read range are determined based on preparation experience,with each uncertainty parameter approximated as an interval set.In the end,experiments are carried out to measure the read range of graphene antennas to verify the proposed algorithm.Results show that the proposed algorithm can calculate the read range of graphene antennas effectively.Thus,this research facilitates the practical use of graphene antennas and provides guidance for uncertainty analysis during manufacture.
