中文摘要：

针对目前射频识别（RFID）天线小型化要求,设计了一种超高频（UHF）弯折偶极子RFID标签天线。天线的构型采用了经典的电感耦合环匹配模型,结构简单且易实现阻抗匹配;在天线宽度上进行二次弯折降低长宽比例,具有小型化优势。利用HFSS仿真软件对该天线进行仿真分析,结果表明该天线具有较宽的阻抗带宽,能够覆盖920~925 MHz超高频频段,并且其回波损耗值及方向性均良好,能够满足RFID的实际生产和应用的要求。

英文摘要：

An ultra high frequency（UHF） bending dipole radio frequency identification（RFID） tag antenna was presented to meet the requirements of the antenna miniaturization. The design adopted classical inductively coupled ring matching model, which had a simple structure and achieved impedance matching easily. Moreover, secondary bend on the antenna width was used to reduce the size of the antenna. The simulation results show that the designed antenna has a wide impedance bandwidth, covering 920 MHz to 925 MHz UHF band, and has a good return loss value and omni-direction, which can meet the practical requirements of RFID tag antenna.
