摘要

摘要: 在解决射频识别(RFID)标签天线设计中阻抗计算速度慢的问题的过程中，针对其中较为复杂的阻抗耦合情况，该文提出一种基于多项式的弯折偶极子RFID标签天线阻抗预测方法。首先使用基于天线尺寸的阻抗变换与线性化假设建立模型假设；然后在具体的天线结构中收集数据并进行相关性分析与回归拟合验证假设正确性；最后实验验证使用该方法进行的阻抗预测相对于计算机仿真的准确性、高效性与普适性。试验结果表明，使用该方法替代计算机进行弯折偶极子RFID标签天线阻抗计算时，其预测阻抗相对于计算机仿真结果在保持较高预测准确率的同时极大地缩短了阻抗计算时间，同时该方法在中国应用频段上针对不同弯折次数的弯折偶极子RFID标签天线仍然适用。

Abstract: In the process of solving the problem of slow impedance calculation speed in the design of Radio Frequency IDentification (RFID) tag antenna, a method of impedance prediction based on polynomial for folded dipole RFID tag antenna is proposed in view of the complex impedance coupling. Firstly, impedance transformation based on antenna size and linearization assumption are used to establish model hypothesis. Then the data are collected from the antenna structure and the correlation analysis and regression fitting are carried out to verify the validity of the hypothesis. Finally, the accuracy, efficiency and universality of the impedance prediction method compared with computer simulation are verified by experiments. The experimental results show that the predicted impedance can greatly shorten the calculation time while maintaining high prediction accuracy when the proposed method replace computer to calculate the impedance of the folded dipole RFID tag antenna, and the method is still applicable to the RFID tag antenna with different bending times in the frequency band used in China.
