摘　　要：无源RFID标签的读写性能主要取决于其天线和芯片的性能,其中超高频RFID标签通常采用偶极子天线。从理论-仿真-实验的角度详细介绍了偶极子天线的设计和优化方法,并制作了4款小型超高频RFID标签样品。测试结果表明,4款样品标签的性能与仿真的优化结果高度一致,该设计和优化方法可行。The read range of passive RFID tags is decided by the properties of the antenna and the IC used by the tag. In UHF RFID systems, the dipole antenna is one of the most used. Based on theoretically analysis, electromagnetic simulation and experiment, this paper presents the design and optimization methods of a small dipole antenna in details. Four prototypes were fabricated. The test results show that the performance of the four tags is in good agreement with the simulation. The design and optimization method is effective.
