摘要

提出了两种用于金属物体标签的微带偶极超高频(UHF) RFID标签天线。该天线结构非常简单，没有短针和短板，由曲线形和阶梯馈线、矩形回线、电容端负载和t型匹配结构组成。此外，两种标签天线设计都插入了完整的接地平面，以确保标签在金属物体上可以正常工作。这些标签被设计在919 - 923兆赫的频率范围内工作，这是马来西亚的频率范围。利用CST仿真软件进行了仿真。对两种标签天线设计在阻抗匹配、反射系数和标签读取范围等方面的仿真结果和实测结果进行了比较和分析。当设计1和设计2标签贴在金属物体上时，测量到的读数范围分别为2.0 m和2.2 m。

Microstrip Dipole UHF-RFID Tag Antenna for Metal Object Tagging

Two designs of microstrip dipole ultra-high-frequency (UHF) RFID tag antenna which can be used for metal object tagging are presented. The antennas, which have a very simple structure without any shorting pin and shorting plate, are composed of meander and ladder feed lines, rectangular loop, capacitive tip-loading and T-match structure. In addition, a full ground plane has been inserted in both tag antenna designs in order to ensure that the tags can work properly when attached on metal object. The tags are designed to operate in the frequency range of 919 - 923 MHz, which is the frequency range of Malaysia. The simulation has been carried out using CST Simulation software. The simulated and measured results of both tag antenna designs in terms of impedance matching, reflection coefficient and tag reading range has been compared and analyzed. The measured reading range obtained when the Design 1 and Design 2 tag attached on metal object is 2.0 m and 2.2 m respectively.
