摘要

提出了一种超高频RFID标签天线的单层结构。该天线可用于金属和非金属表面。该天线在连接到金属表面时作为微带天线工作，在连接到非金属表面时作为偶极子天线工作。天线设计在厚度为1.52 mm的Teflon衬底上，以匹配NXP UCODE G2XL。rfid芯片阻抗是一个1385欧姆的电阻与一个1.16 pF的电容并联，在922.5 MHz时阻抗为16-j147欧姆。给出了模拟天线的阻抗和天线的读数范围。

Simulated results for single layer dual mode antennas for UHF RFID tag using open stubs

This paper proposes a single layer structure of a tag antenna for UHF RFID. The antenna can be used in both metallic and non-metallic surfaces. The antenna operates as a microstrip antenna when it is attached to a metallic surface and operates as a dipole antenna when it is attached to a non-metallic surface. The antenna is designed on Teflon substrate with the thickness of 1.52 mm to match NXP UCODE G2XL. The RFID-chip impedance is a resistor of 1385 ohm in parallel with a capacitor of 1.16 pF. This gives the impedance of 16-j147 ohm at 922.5 MHz. The simulated antenna impedance and reading range of the antenna are reported.
