摘要:: 为了使射频识别(radio frequency identification,RFID)系统的标签能够应用到低价值商品，降低射频电子标签成本,设计了一种类条形码的无芯片电子标签。该标签由介质基板上刻蚀一系列长度相同、宽度不同的微带缝隙组成，类似于光条形码结构。采用4-bit的编码结构，验证了几种典型的编码状态无芯片标签设计的准确性和有效性，并通过增加长度不同的谐振器组扩展编码容量。这种结构的无芯片标签有取代目前流行的条形码的潜力，能够实现低价格商品的自动识别，无需人工干预，在应用中节省了人力、物力和时间。

Abstract:: In order to make the tags of the radio frequency identification (RFID) system be applied to low-cost goods,reducing the cost of radio frequency electronic tags,a barcodelike chipless electronic tag is designed.The chipless tag is composed of a series of microstrip slots with the same length and different widths etched on the dielectric substrate,which is similar to the optical barcode structure.The experiment adopts 4-bit encoding structure to verify the accuracy and validity of several chipless tag designs for coding states.The encoding capacity can be expanded by adding resonator groups with different lengths.In addition to saving labor,material resources and application time,the chipless tag suggested in this research has the potential to replace the already widely used barcodes and achieve automatic identification of inexpensive goods without human involvement.
