摘要

提出了一种用于超高频频段射频识别的超材料无源标签天线设计方案。所提出的标签天线设计包括一种弯曲技术，使天线与标签芯片相匹配，以及一个互补的分裂环谐振器，以减少天线的尺寸。该标签天线采用了介电常数为3.3、损耗正切为0.04、厚度为0.25mm的先进photoppaper衬底。采用ADS对所设计的标签天线尺寸进行了优化，电路总尺寸为84.6 × 28mm2。基于增益、回波损耗、匹配输入阻抗和读取范围对所提标签天线的性能进行了评估和分析。915MHz时的模拟反射系数约为−35dB，阻抗带宽约为32.8MHz，增益为1.8dB，读取范围约为6.2 m。

A novel design of passive UHF RFID tag antenna mounted on paper

In this paper, a novel design of metamaterial passive tag antenna for radio frequency identification operating in the UHF band is proposed. The design of the proposed tag antenna included a meandering technique to match the antenna with the tag chip and a complementary split ring resonator to reduce the antenna size. An advanced Photopaper substrate having a permittivity of 3.3, loss tangent of 0.04 and thickness of 0.25mm is used to design this tag antenna. The dimensions of the proposed tag antenna are optimized by using ADS. The total size of this circuit is 84.6 × 28mm2. The performance of the proposed tag antenna is evaluated and analyzed based on gain, return loss, matching input impedance and read range. The simulated reflection coefficient is about −35dB at 915MHz, the impedance bandwidth is about 32.8MHz, gain is 1.8dB, and the read range is about 6.2 m.
