一种带宽改进的UHF频段RFID标签天线
Bandwidth-enhanced Antenna for UHF RFID Tags
标签天线的性能对整个射频识别系统的工作指标有关键性的作用。为了减小环境的影响，需要增加天线的带宽。本文对UHF频段普通偶极子天线进行改进，设计了一种带宽改进的RFID标签天线，尺寸为92×24mm。使用有限元法进行仿真，同时也给出了实际测试的结果。测试结果为：当驻波比小于2时，带宽为218MHz（802MHz-1.02GHz），符合UHF频段要求，相对带宽为24.7%。测试结果与仿真结果较符合。
ag antenna plays an important part in the radio frequency identification system. In order to reduce the environmental effect, we need to increase the bandwidth of the antenna. In this paper, the bandwidth of general UHF band dipole antenna was improved, the new RFID tag antenna is of size 92 × 24mm. The finite element method was used in simulation, and the actual test results were also given. Test results: When VSWR is less than 2:0, the bandwidth is 218 MHz (802MHz-1.02GHz), which meets the requirements of the UHF band, the relative bandwidth is24.7%. Simulation results and the test results are in good agreement.
