摘要

在本文中，我们证明了一个细长的金属结构可以作为无源超高频RFID系统的近场天线，该系统包括一个安装在结构上的金属标签和一个直接的电馈送到结构上，用于传输阅读器到标签信号和接收标签响应。结果表明，传统的金属安装标签可以在距离结构馈送点30 m处读取，远远超过金属安装标签的最大远场自由空间范围。

RFID system exploiting large metal objects as near field UHF RFID antennas

In this paper, we demonstrate that a long thin metal structure can act as as a near-field antenna for a passive UHF RFID system comprising a metal mounted tag on the structure and a direct electrical feed onto the structure for both transmission of reader to tag signals and reception of the tag response. It is shown that a conventional metal mounted tag can be read up to 30 m away from the feed point on the structure far exceeding the maximum far field free space range of the tag mounted on metal.
