摘　　要：近年来,自动识别方法在许多服务领域,诸如货物采购与分配、商业贸易、生产制造和物流等领域中,得到了快速地普及和推广。自动识别的任务和目的是提供关于个人、动物和商品的信息。自动识别系统克服了标签存储容量小和不能改写的缺点。自动识别系统在数据载体与一个所属阅读器之间进行非接触式传输。根据自动识别系统使用的能量和数据传输方法,我们把非接触式识别系统称为RFID系统。RFID系统是通过阅读器与标签之间的天线之间交换能量来读取数据的。常用于RFID系统中的天线有偶极天线、Yaugi-Uda天线、片状或微带天线和缝隙天线。In recent years,RFID has been quickly popularized and used in many service field like purchase,distribution,commercial,manufacture,logistics and other fields.The tasks and aims of RFID is providing the information of individuals,animals and goods.RFID system overcomes the problem that the label cannot store much information and cannot rewrite information.RFID system non-connect exchange information between data carrier and the reader.Accord to the method how the RFID system uses energy and change information.We called the non-connect identification system RFID system.The reader reads information from data carrier by exchange energy.The common antennas used in RFID system are dipole antenna,yaugi-uda antenna,patch antenna,microstrip antenna and slot antenna.
