摘要
为了在物流中普及射频识别(RFID)标签,降低RFID标签成本,设计了一种基于频域的四边形开口谐振器无芯片RFID标签。标签可使用微电子打印机进行打印制作。在较小的尺寸中,设计出包含8 bit数据容量的标签。标签由两条平行对称天线、四边形开口谐振器、矩形介质基板组成。四边形开口谐振器产生一个电阻—电感—电容(RLC)谐振电路,通过改变L和C的结构,可以使谐振结构产生不同谐振中心频率。采用三维电磁仿真软件高频结构仿真器(HFSS)对标签进行仿真,并采用2个平行对称天线对标签进行测试。仿真和测试结果表明:标签在1~7 GHz的频带范围内能够实现ID编码,并具有良好的灵敏度、重现性和线性度。设计的标签结构和制作工艺简单,具备成本低、无需维护、可重复使用等优点。
In order to make radio frequency(RFID)tag popular in logistics and reduce the cost of RFID tag,a quadrilateral open resonator chipless RFID tag based on frequency domain is designed.The tag can be printed using a microelectronic printer.A tag with 8-bit data capacity is designed in a small size.The tag consists of two parallel symmetrical antennas,a quadrilateral open resonator and a rectangular dielectric substrate.The quadrilateral open resonator generates a resistor-inductor-capacitor(RLC)resonant circuit.By changing the structure of L and C,the resonant structure can produce different resonant center frequencies.Three-dimensional electromagnetic simulation software high-frequency structure simulator(HFSS)is used to simulate the tag,and two parallel symmetrical antennas are employed for testing.The simulation and test results show that the tag can realize ID coding in the frequency band range of 1~7 GHz,and has good sensitivity,reproducibility and linearity.The designed tag features a simple structure and fabrication process,along with advantages such as low cost,no need for maintenance,and reusability.
