折叠偶极子阵列无芯标签及其识别

Folded dipole array-based chip-less tags and its identification

针对传统电子标签的单片价格高、功率需求大等问题,在具体分析了基本谐振单元的基础上提出了一种折叠偶极子阵列无芯标签。该类标签是不包含任何其他组件的散射体结构,利用谐振体在特定频点上的谐振特性,以不同物理参数谐振单元组合的方式产生特定的散射场频域特性。对多个标签结构的极点参数进行了分析和仿真,结果表明,基于标签极点的识别方式具有可行性。

To overcome issues of traditional chipped tags in terms of high unit cost as well as lager power demand, a folded dipole array based chip-less tags is proposed on the basis of eoncrete analyzing to fundamental resonant cell. The chip-less tags is, in essence, a scattering structure contained no any other components. With the knowledge that particular characteristic of a reso- nance oceurring in knowing frequency point, specific frequency-domain characteristic of scattering field is obtained by combination the resonant unit with different physical parameter. Due to the nature of pole, toughly assoeiated with target shape and material, dif- ferent tag structure generates various poles distribution. Through accurate analysis to the pole parameters of multiple structure tags, simulation results show that the target pole based identification method is feasibility.
