摘要
在射频识别(RFID)领域,由于UHF频段无源RFID电子标签读写距离远、价格低、寿命长等特点,该频段RFID技术受到世界各国的广泛重视。本文首先介绍UHF频段RFID系统工作原理,然后进行该频段RFID系统的干扰分析并量化分析干扰对RFID读写距离的影响,最后给出UHF频段RFID技术的干扰抑制和部署策略,对该频段RFID技术的应用普及具有重要意义。
Because of character of far accessing distance, low price and long life-span of electronic tag, many countries are attracted to UHF passive RFID technique. On the first hand, principle of UHF passive RFID system is introduced. On the second hand, interferences to UHF RFID system and accessing distance are analyzed. On the last hand, interference suppression and deployment strategy are given, and are meaningful to popularize application of UHF passive RFID technique.
