摘要
设计分析了一种圆环开槽型的无芯片射频识别RFID(Radio Frequency Identification)标签。这种圆环开槽型结构具有高度的对称性,无需考虑入射波的极化方式。对散射得到的时域信号进行极点的提取。根据极点与标签结构的对应关系,主要极点提供了嵌入在标签结构中的基本数据,通过主要极点来对标签的结构进行识别。通过仿真分析可知,这种标签结构可达到4 bit的编码,可成为一种新型无芯片RFID标签结构。
A novel slotted ring chipless radio frequency identification tag is designed and analysed. This tag has a high degree of symmetry, needn＇t to consider the polarization of the incident wave. The pole is extracted from the scattering of time-domain signal. According to the corresponding relationship between the pole and tag, the domain pole provided the basic data that is embedded in tag structure. Through simulation analysis, the tag is identified by the domain pole. Tag can encodes up to 4 bit , it becomes a new chipless RFID tag.
