摘　　要：基于RFID系统对天线的要求,提出了一种适用于UHF频段上的RFID读写器天线。该天线采用背馈馈电方法,通过在分形结构上采用非对称矩形切角来实现天线的小型化和圆极化。利用电磁仿真软件分析了天线性能,仿真与测试结果吻合良好。Based on the requirements of the radio frequency identification （RFID） systems, a new antenna for U HF RFID reader is proposed. The antenna uses the back-feeding pattern and the asymmetric rectangular corner truncated design on fractal geometry to realize miniaturization and circular polarization of the antenna. The electromagnetic simulation software is adopted for analyzing the performance of the designed antenna. And the simulation results are in good agreement with the measured results, which verified the reliability of the designed antenna.
