摘要:

提出了一种用于金属物体表面的RFID天线。该天线包含一个耦合地板和翼型辐射贴片。天线尺寸为84 mm×25 mm×4.5 mm,当圆极化阅读器天线增益为7.5 dBi,辐射功率为30 dBm时,在902~928 MHz范围内阅读距离可达10 m。标签天线在金属物体表面的实测结果显示,该标签具有较好的远距离识别性能。

关键词: 标签天线, 抗金属, 耦合结构

Abstract:

This paper presents a novel RFID tag antenna for metallic objects.This antenna contains a coupling ground and wing-shape radiation patch.The antenna has the compact size of 84 mm×25 mm×4.5 mm.If the Circularly polarized reader antenna gain is 7.5 dBi,the radiated power is 30dbm,the reading distance can be reached to 10 m in 902~928 MHz range.The measured results indicate that the tag antenna has a good long-range recognition performance on the surface of the metal objects.

Key words: tag antenna;anti metal;coupling structure
