基于无源RFID标签天线的印刷质量评价模型研究

Study of Printing Quality Evaluation Model of Passive RFID Tag Antennas

为评价无源RFID标签天线的印刷质量,对无源RFID标签天线的质量性能进行了理论分析。针对成品后的天线性能与仿真后的天线性能间存在的差异,在丝网印刷的条件下,以RFID标签天线间的间隙偏差、天线厚度偏差和最大阅读距离偏差为自变量,建立了评价无源RFID标签天线印刷质量的数学线性回归模型,为RFID标签天线在生产过程中的优化提供了一定指导。

The quality performances of passive RFID tag antennas were analyzed in theory.According to the differences between the measured and simulation of antenna performance,under screen printing conditions,Linear regression model was established using the gap,thickness and maximum reading distance as three independent variables to evaluate the printing quality of RFID tag antennas.The purpose was to provide guidance for optimization of RFID tag antennas in practical production.
