摘要
目的:通过印刷法制作柔性UHF RFID标签,实现RFID标签的可拉伸性,将其应用到可穿戴电子领域。方法:通过ADS仿真分析和公式计算两种方法得出RFID标签芯片的输入阻抗,并根据标签芯片的输入阻抗值用HFSS设计出一款基于半波偶极子天线的UHF RFID标签天线,最后通过印刷法制作出了可拉伸RFID标签实物。结果: UHF RFID标签天线的中心频率为890 MHz,在全频带(860~960 MHz)范围内的 S 11 小于-10 dB,符合设计要求。结论:柔性可拉伸RFID标签测试结果与仿真结果一致,且在反复拉伸 1 000 次后仍能保持将近7 m的读取距离,故可以应用于可穿戴电子领域。
Aims: To fabricate flexible UHF RFID tags by the printing method and apply to the field of wearable electronics. Methods: The input impedance of the RFID tag chip was obtained by ADS simulation analysis and formula calculation. The UHF RFID tag antenna based on the half-wave dipole antenna was designed by HFSS according to the input impedance value of the tag chip. A stretchable RFID tag was fabricated by the printing method. Results: The center frequency of the UHF RFID tag antenna was 890 MHz;and the S 11 in the full band (860~960 MHz) range was less than -10 dB, which met the design requirement. Conclusions: The measurement results of the stretchable RFID tags are consistent with the simulation results. The reading distance of the tag is about 7 m after repeatedly stretching for 1 000 times. It can be applied to the field of wearable electronics.
