Problems solved by technology

[0005] The purpose of the present invention is to provide a dual-capacitance radio frequency soft label, which solves the problem of the existing high-precision soft label. The wires forming the capacitance area are equal in width, and the capacitance wires on the front and back can only form a single capacitor, which is not conducive to improving The technical problem of the capacity of the capacitance area further improves the accuracy of the radio frequency soft label, which is beneficial to the work of anti-theft and anti-counterfeiting

Embodiment 2

[0030] A dual-capacitance radio frequency soft tag firstly has the same dual-capacitor structure as in Embodiment 1. In addition, the widths of the capacitor wires and the coil wires gradually decrease from outside to inside. It should be noted that the width of the back capacitor wire is not larger than that of the front capacitor wire. With this structure, the capacity of the capacitive area can be effectively increased, and the inductance of the coil can be increased, which helps to improve the use accuracy of the radio frequency soft label.

Embodiment 3

[0032] A double-capacitance radio frequency soft label is a further improvement on the basis of Embodiment 2. Wherein, the insulating film layer and the conductive layer together constitute the base layer of the label, and a hard insulating material layer is arranged on the base layer, and the hard material layer has a pre-processed breaking mark, and the breaking mark has an intersection angle with the circuit on the conductive layer.

[0033] The structure of Example 3 is based on Example 2 with a snap-off non-revivable structure added. After the label is used, the label can be broken through the breaking mark. At this time, the breaking fracture of the hard material can cut off the intersecting line on the conductive layer, so that the label is completely scrapped and the label is prevented from being revived.

[0034] In order to enhance the effect of embodiment 3, the breaking mark has an intersection angle with the capacitor wire on the conductive layer.

Embodiment 4

[0039] A dual-capacitance radio frequency soft tag also has a dual-capacitance structure as in Embodiment 1. In addition, both the front conductive layer and the back conductive layer of the label have capacitor wires and coil wires, thereby forming a soft label with double-sided circuits. Through this structure, the inductance of the coil part can be further increased, and the precision of the product can be improved.
