摘要

本文介绍了一种小型超高频射频标签天线的设计，采用了多种微型化技术，包括弯曲技术和电容式尖端加载结构。此外，在天线设计中还采用t匹配技术进行阻抗匹配。该天线设计在Rogers 5880印刷电路板(PCB)上，尺寸为43 × 26 × 0.787 mm3，相对介电常数□r为2.2。通过在CST Microwave Studio软件中进行仿真，从匹配阻抗、天线增益、回波损耗和标签读取范围等方面分析了该天线的性能。结果表明，该天线在921 MHz时的增益为0.97dB，最大读取范围为5.15 m。

UHF-RFID tag antenna with miniaturization techniques

This paper presents the design of a compact UHF-RFID tag antenna with several miniaturization techniques including meandering technique and capacitive tip-loading structure. Additionally, T-matching technique is also utilized in the antenna design for impedance matching. This antenna was designed on Rogers 5880 printed circuit board (PCB) with the dimension of 43 × 26 × 0.787 mm3 and relative permittivity, □r of 2.2. The performance of the proposed antenna was analyzed in terms of matched impedance, antenna gain, return loss and tag reading range through the simulation in CST Microwave Studio software. As a result, the proposed antenna obtained a gain of 0.97dB and a maximum reading range of 5.15 m at 921 MHz.
