摘　　要：为降低传统标签的成本,提出基于微带耦合的可重发无芯片标签.具有窄带固定带宽的谐振器采用C型微带反向嵌套来提高单个谐振器的Q值,提高频谱的利用率.为验证所提出的结构,设计8 b的C型微带反向嵌套谐振器耦合的无芯片标签,仿真和测试结果表明了该设计的准确性和可行性.在可用的频带上,采用频率位置调制的编码技术后,编码容量可达到17 b,还验证了各种物理结构参数对标签编码容量的可扩展特性.这种标签可用于物流业,超市等领域替代条形码.In order to decrease the cost of the traditional tags,a chipless tag based on microstrip coupling retransmission is proposed.The resonator which has narrowband fixed bandwidth utilized C-shaped microstrip reverse embedding to increase the Q of a single resonator for impoving the spectrum utilization.To validate the proposed structure,an 8 bits C-shaped microstrip reverse embedded resonators coupling with microstrip transmission line be designed.The results of simulation and measurement are shown the accuracy and feasibility of the design.The coding capacity is up to 17 bits on the operating bandwidth.Finally,the scalable nature of the various physical structure parameters to the tag encoding capacity was also verified.This kind of tag can be used in the logistics industry,supermarkets and other fields to replace the barcodes.
