    摘要:

    针对UHF RFID标签贴附在介质表面时,标签的谐振特性用接触式测量方法存在较大的误差问题,通过建立标签的接收功率模型,分析标签芯片获取到的能量与频率之间的关系,提出非接触式测试UHF RFID谐振特性的方法。详细描述了利用频率和距离关系测试标签谐振特性的原理,说明了非接触式测试方法硬件测试平台的搭建方法和测试软件的编写思想,并完整地实现了该平台。实测实验证明,该测试方法和平台能有效地测试标签的谐振特性。在实际应用中,可以根据标签的谐振特性设计适合不同物体的标签。

    Abstract:

    While UHF RFID tags being attached to the surface of various materials, there will be great errors when we adopt the traditional method of cable connection test to get the tags resonance characteristics. In this paper, we formed a model of tags powerreceiving, analyzed the relationship between the energy obtained by tag chip and frequency, and then proposed a contactless method to get the resonance characteristics of UHF RFID tags. This paper detailed the principle of using the relationship between frequency and distance to test the resonance characteristics, illustrated the design concept of testing software, built and completely implemented the contactless hardware test platform. Measurement results demonstrated that the proposed method and platform can test the tags resonance characteristics effectively. In practical applications, tags for different materials can be designed according to the resonance characteristics.
