摘要
标签极点提取的准确性受多种因素影响,以折叠偶极子阵列无芯标签为研究对象,开展无耗电介质材料(厚度、相对介电常数)对其极点分布的特性分析。仿真结果表明,随着介质厚度及其相对介电常数的增大,谐振极点的衰减因子及谐振频率将呈现变小的趋势,极点分布以类S型曲线向坐标原点靠近。
The accuracy of the tag pole extraction is affected by many factors, and the pole distribution characteristics of loss-less dielectric media materials （thickness, relative permittivity） is analyzed. Using folded dipole array chipless tags as a research ob-ject. Simulation results show that the damping coefficient and resonance frequency of resonance pole tend to decrease while the pole distribution performed S-shaped similar curve close to axis origin with the dielectric thickness and relative dielectric constant in-creases.
