摘要

提出了一种与意法半导体XRAG2无源标签集成电路相匹配的超高频RFID标签天线结构。该设计在PET(聚对苯二甲酸乙二醇酯)衬底上实现，其整体尺寸为82.5 mm × 45.29 mm。仿真结果表明，所设计之字形天线在谐振频率为−39 dB处的回波损耗和全向辐射特性，最大增益约为1.97 dBi，远优于初始弯曲偶极子天线。通过罗德与施瓦茨公司的ZVB矢量网络分析仪对天线样机进行了测试，结果与仿真结果吻合良好。

Improving radiation characteristics of UHF RFID antennas by zigzag structures

An antenna structure for UHF RFID tag matched to ST Microelectronics XRAG2 passive tag IC is proposed in this paper. The design is realized on PET (Polyethylene Terephthalate) substrate that has the overall dimension of 82.5 mm × 45.29 mm. The simulation shows that the proposed zigzag-shaped antenna has the return loss at the resonant frequency of −39 dB and omni-directional radiation characteristics with the maximum gain of about 1.97 dBi that is much better than that of the initial meander dipole. The prototype antenna was tested by Rohde & Shwarz ZVB Vector Network Analyzer and showed good fit with the simulation results.
