Abstract

Radio frequency identification (RFID) technology holds promise for managing products through their lifecycle. Passive RFID tags can be read at a distance and do not require a line of sight between tag and reader. This paper identifies the technical parameters that harm RFID performance and evaluates measures to enhance performance. Issues addressed include read range, algorithms for communication between tag and reader, the process by which the tag modulates the carrier signal, the theory behind powering a passive tag via a LC circuit antenna, and the algorithm for simultaneously receiving and decoding information from more than one tag.

感应式RFID技术的优化

无线射频识别(RFID)技术有望在产品的整个生命周期内对其进行管理。无源RFID标签可以在一定距离上读取，并且不需要标签和阅读器之间的视线。本文确定了影响RFID性能的技术参数，并评估了提高性能的措施。所讨论的问题包括读取范围，标签和阅读器之间通信的算法，标签调制载波信号的过程，通过LC电路天线为无源标签供电的理论，以及同时接收和解码来自多个标签的信息的算法。
