提出了一种用于金属物体的超高频射频识别标签天线，该天线适用于多标准超高频射频识别系统。采用在偶极子结构上增加环形微带线来增大输入阻抗，极大地提高了标签天线的增益特性。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。整个天线的面积为100 mm×40 mm，由于采用表面印刷结构，使得标签成本低廉、易于批量生产。
提齣瞭一種用于金屬物體的超高頻射頻識彆標籤天線，該天線適用于多標準超高頻射頻識彆繫統。採用在偶極子結構上增加環形微帶線來增大輸入阻抗，極大地提高瞭標籤天線的增益特性。利用電磁倣真軟件分析瞭天線性能，倣真與測試結果吻閤良好。整箇天線的麵積為100 mm×40 mm，由于採用錶麵印刷結構，使得標籤成本低廉、易于批量生產。

An ultra high frequency(UHF)radio frequency identification(RFID)tag antenna for metallic objects is presented. The antenna is applied to multi?standard UHF RFID system. The antenna is fabricated on a thin flexible PET substrate with the thickness of 1 mm. A loop microstrip line is added in the dipole antenna structure to enhance input impedance,which improved the gain characteristic of the antenna immensely. Based on simulated model,The antenna performance is analyzed with electro?magnetic simulation software. The measured results are in good agreement with simulated results. The area of the whole antenna is 100 mm×40 mm. The tag obtains the advantage of low cost and can be mass?producd due to its printed structure.
