Description

Technical Field

[0001] The utility model relates to the technical field of metal label design, in particular to an RFID flexible anti-metal label. Background Art

[0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology that receives and transmits signals through electromagnetic conversion. It has been widely used in supply chain and other fields, accelerating information transmission in different links of various fields. RFID electronic tags are often used in metal environments. Metal has strong reflectivity to electromagnetic waves, and the reflected electromagnetic waves are opposite in phase to the incident electromagnetic waves and of similar magnitude. Therefore, the electromagnetic signal is weak and basically cannot reach the minimum power requirement for activating the tag chip, resulting in the RFID tag not working. At present, the general solution is to stick a thick layer of foam material on the back of the electronic tag to increase the distance between the tag and the metal surface, thereby reducing the metal's reflectivity to the tag. This method results in a large label and poor anti-metal effect.

[0003] Flexible anti-metal tags are not only used on flat metal surfaces, but also have excellent performance on curved metal assets. At the same time, they can meet customers' customized printing and coding needs. However, due to the limitations of their structure and production process, their product size is larger and their performance is worse than anti-metal tags of the same size. In the prior art, flexible RFID anti-metal tags have problems such as reduced antenna electrical length and antenna gain due to the separation structure of the reflective layer and the radiation layer, poor product performance, complex processing difficulty, and are not conducive to mass production and roll printing. Improving the performance of flexible anti-metal tags and reducing their product size are the difficulties in research and development at this stage.
