摘要

在一些射频识别(RFID)应用中，RFID标签天线将被打印到柔性基板上。在粘贴到不同的物体上后，由于标签的灵活性，可能会对标签天线造成扭曲，如标签的弯曲。本文主要研究无源射频识别系统中射频标签天线弯曲对系统性能的影响。使用的天线是基本折叠偶极子。仿真结果表明，以工作范围为特征的无源RFID系统的性能会因失真而显著下降。因此，对于可能发生这种影响的RFID系统，应该考虑对这种影响不太敏感的天线结构。

Performance degradation of RFID system due to the distortion in RFID tag antenna

In some Radio-Frequency IDentification (RFID) applications, the RFID tag antennas will be printed onto flexible substrates. After sticked onto different objects, possible distortion to the tag antenna such as bending of the tag will be caused due to the flexibility. In this paper, performance degradation of passive RFID systems due to bending of the RFID tag antenna is investigated. The antenna used is the basic folded dipole. Simulation results show that the performance of a passive RFID system, characterized by operating range, can be degraded significantly due to distortion. Thus, antenna structures less sensitive to this should be considered for RFID systems where this kind of effect might occur.
