摘要

本文介绍了一种用于金属表面应用的微型PIFA RFID标签天线。RFID标签天线具有紧凑的尺寸($45\text{mm}\times 45\text{mm}\times 5.162\text{mm}$) UHF，具有4.2dB的高增益和25m的最大读取范围。所设计的天线为双基板PIFA，其辐射面由铜制成，印刷在Rogers RT / duroid 5880 ($\varepsilon_{r}=2.2,\ \text{tan}\ \sigma=0.0009$)上，人工磁性导体(AMC)和接地面分别印刷在FR4环氧基板($\varepsilon_{r}=4.4,\ \text{tan}\ \sigma=0.02$)的顶部和底部。天线连接到阻抗为$\mathrm{Z}=13.6-\mathrm{j}\ 127$的Monza R6芯片，频率为866 MHz。它覆盖了780兆赫(570兆赫-1.35 GHz)的带宽，因此它覆盖了整个欧洲UHF RFID频段。为了测试其鲁棒性，在不同的金属板上模拟了该标签天线，但这些金属板不影响标签的性能。

Miniaturized PIFA RFID UHF Tag Antenna for Metal Surface Applications

A miniature PIFA RFID tag antenna for metal surface applications is presented in this article. The RFID tag antenna has a compact size ($45\text{mm}\times 45\text{mm}\times 5.162\text{mm}$) UHF, with a high gain of 4.2dB and a long maximum read range of 25m. The designed antenna is a two-substrate PIFA whose radiating plane, made of copper, is printed on Rogers RT / duroid 5880 ($\varepsilon_{r}=2.2,\ \text{tan}\ \sigma=0.0009$), the artificial magnetic conductor (AMC) and the ground plane are printed on top and bottom of FR4 epoxy substrate ($\varepsilon_{r}=4.4,\ \text{tan}\ \sigma=0.02$) respectively. The antenna is connected to the Monza R6 chip of impedance $\mathrm{Z}=13.6-\mathrm{j}\ 127$ at 866 MHz. It covers a bandwidth of 780 MHz (570 MHz-1.35 GHz) and therefore it covers the entire European UHF RFID band. To test its robustness, this tag antenna is simulated on different metal plates but these do not affect the performance of the tag.
