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, the automatic identification method has been rapidly popularized and popularized in many service areas, such as purchasing and distribution of goods, commerce and trade, manufacturing and logistics. The task and purpose of automatic identification is to provide personal, animal and commodity information. Automatic identification system to overcome the label storage capacity is small and can not be rewritten shortcomings. Automatic identification system in the data carrier and a reader to contact between non-contact transmission. According to the energy and data transmission methods used by the automatic identification system, we refer to the contactless identification system as the RFID system. The RFID system reads data by exchanging energy between the reader and the antenna between the tags. Antennas commonly used in RFID systems are dipole antennas, Yaugi-Uda antennas, patch or microstrip antennas, and slot antennas.
