摘要
RFID隶属于非接触的自动识别技术。RFID系统在工业和商业中得到广泛的应用，系统基本原理是利用射频信号和空间电磁场耦合传输特性，来实现对监控物体的信息交换及自动识别。系统一般包括两部分，即电子标签（Tag）和阅读器（Reader）。标签激活距离是衡量一个RFID系统性能的重要因素。该文详细解释了RFID工作原理和推导出影响标签激活距离的参数。研究对象是高频（HRF）13．56MHz的RFID系统。
Radio Frequency Identification （RFID） is a relatively new technology. However, RFID has been found in my applications within the industrial field, business field and so on. RFID system consists of Reader and Tag. Reader and tag can transmit information to each other through coupling. Active distance of RFID tag that can reflect the performance of the system is an important factor. And now, we explain the system principle in detail and deduce which factors affected the active distance. In addition, the paper is to the HRF 13.56 MHz RFID system.
