摘　　要：提出了一种新的LF/HF RFID阅读器天线设计,以扩大RFID阅读器检测标签的范围。研究的结构是一种基于改进的磁力线分布和方向的球形天线,通过新的磁力线场分布,可以检测更多不同角度和方向的标签。利用Maxwell电磁场仿真软件对此几何结构的线圈进行仿真分析。结果表明,优化后的天线具有更宽广的标签检测范围,证明了方案设计的正确性。A new antenna design of LF/HF RFID reader is proposed to expand the range of RFID reader detecting tags. The structure studied is a spherical antenna based on the improved magnetic field distribution and direction. Through the new magnetic field distribution, more labels with different angles and directions can be detected. Maxwell electromagnetic field simulation software is used to simulate and analyze the coil with this geometric structure. The results show that the optimized antenna has a wider label detection range, which proves the correctness of the scheme design.
