一种双极化结构的新型无芯标签设计

Design of a novel dual-polarized chipless RFID tag

提出了一种由水平和竖直方向上蚀刻的Ⅰ型谐振体构成的双极化无芯RFID新型标签。采用双极化编码技术和频移编码技术设计了该种新型标签的编码方法,实现了编码容量加倍,同时在减少谐振单元的情况下,仍然可获得更加理想的编码容量。最后,设计了一个16 bit的双极化无芯标签,通过仿真验证了其可行性,为无芯标签的研究提供了新的思路。

A novel dual-polarized chipless RFID tag is proposed, which consists of horizontally and vertically polarized ‘ I ＇ shaped resonators. The encoding method is designed by using dual-polarized encoding technique and the frequency shift encoding tech-niques and the encoding capacity is doubled, while reducing the number of resonators more ideal encoding capacity can still be ob-tained. Eventually, a 16 bit dual-polarized chipless RFID tag is designed, and its feasibility is verified by simulation. It provides a new idea for the research of chipless RFID tag.
