Abstract

The invention discloses a no-chip tag structure, and the structure comprises a dielectric plate, wherein the surface of the dielectric plate is provided with at least one multi-ring nested paster unit. The multi-ring nested paster unit comprises a plurality of concentric annular pasters with different internal diameters and different external diameters. The structure provided by the invention aimsat the problems existing in the prior art, and the surface of the dielectric plate is flexibly provided with the multi-ring nested paster unit. The structure is small in size, is low in cost, is large in code capacity, and is high in code density.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification electronic tags, in particular to a chipless tag structure. Background technique [0002] With the development of radio communication, the demand for tracking and positioning and target identification is gradually increasing. In short-distance or indoor communication environments, radio frequency identification technology is widely used. Radio Frequency Identification (RFID for short) refers to the technology that radio frequency signals transmit information through energy propagation, automatically identify target objects and obtain useful data. [0003] In RFID technology, tags have the advantages of long life, small size, large capacity, and reusability. However, due to the high cost of the label, its commercial production is very limited. A common label usually includes two parts, the antenna and the chip. The chip is the main source of the cost of the entire label. Re...
