Embodiment Construction

[0018] see Figure 1-2 , which are structural schematic diagrams of a dual-frequency electronic tag with low frequency and ultrahigh frequency according to the present invention. As shown in the figure: the base layer of the label is composed of an insulating film layer and a conductive layer attached to the insulating film layer. The conductive layer is composed of 8.2MHz low-frequency label lines arranged in the middle and 860-950MHz ultra-high frequency label lines arranged on the periphery of the low-frequency label lines; the low-frequency label lines are composed of decoding points 1, 6, low-frequency coils 4 and Composed of capacitors 2 and 7; the UHF label circuit is composed of a high frequency coil 3 and a chip binding circuit bound with a UHF chip 5 . The capacitor 2 in the low frequency label circuit is located in the low frequency coil 4 . The insulating film layer is PET or PTN, and the thickness of the insulating film layer is 1-100 μm. The conductive materia...

Abstract

The invention relates to the technical field of security tags, in particular to a double-frequency tag with low frequency and ultrahigh frequency. The base layer of the tag comprises an insulating film layer and a conducting layer attached to the insulating film layer. The invention is characterized in that the conducting layer comprises a 8.2MHz low frequency tag circuit arranged in the middle and a 860-950MHz ultrahigh frequency tag circuit arranged on the periphery of the low frequency tag circuit; the low frequency tag circuit comprises a decoding point, a low frequency coil and a capacitor; and the ultrahigh frequency tag circuit comprises a high frequency coil and a chip binding circuit which binds ultrahigh frequency chips. The double-frequency tag solves the technical problem that the existing tags depend on own decoding circuits, only have simpler anti-counterfeit identification functions and are only suitable for the 8.2MHz low frequency environment (decoding equipment). The double-frequency tag not only has the capability of processing more complex information, but also increases the storage amount of the information.

Description

Technical field: [0001] The invention relates to the technical field of electronic safety labels, in particular to a dual-frequency electronic label with low frequency and ultrahigh frequency. Background technique: [0002] With the development of electronic technology, electronic tags with security and anti-counterfeiting functions have gradually entered our lives. They also have the advantages of high sensitivity, small size, and low cost. [0003] For example, the Chinese invention patent specification (authorized announcement number: CN100423026C) discloses a high-precision radio frequency soft label. The base layer of the label is composed of an insulating film layer and conductive layers attached to the front and back of the insulating film layer respectively. The conductive layer has a decoding circuit composed of capacitors, wires and decoding points. The periphery of the coil is characterized in that: the width of the capacitor wire and the coil wire gradually decr...
