一种基于二维相控阵天线的RFID定位方法
An RFID Tag Localization Based on Phased Array Antenna
摘要
Abstract
In radio frequency identification(RFID) systems,excepting to identify the basic information of target,how to additionally aware the precision position of the target is an important and pressing research topic.In this paper,we propose a novel range free tag localization scheme based on phased array antenna for RFID system,called PATL.This method takes advantage of the adjustable radiation angle of the phased array antenna to scan the surveillance region in turns.By using the statistics of the tags' number in different antenna beam directions,a weighting algorithm is used to calculate the position of the tag.This method can be applied to real-time location of multiple targets without usage of any reference tags or additional readers.We use a COTS U-HF RFID reader which is integrated with a phased array antenna to evaluate our method.The results show the average is about 21cm and the time consumption also satisfy the real time performance.关键词
