Problems solved by technology

[0005] The third problem in tag antenna design is the influence of metal objects. Since metal will reflect electromagnetic waves, it will cause destructive interference to the characteristics of adjacent RFID tag antennas, thereby affecting its reading performance
For example, if the label is directly attached to the metal, it will be completely impossible to read the label

Abstract

The invention relates to a radio frequency identification tag and a label paper product applying the same. The radio frequency identification tag comprises a signal source structure, a radiation structure, an isolation structure and a base material, wherein the signal source structure comprises a loop antenna and a radio frequency identification chip, and the radio frequency identification chip iselectrically connected to the loop antenna; the radiation structure surrounds the signal source structure; the isolation structure is arranged at one side of the radiation structure at an interval; and the base material is used for bearing the signal source structure, the radiation structure and the isolation structure.

Description

technical field [0001] The invention relates to a label, in particular to a radio frequency identification label and a label paper product using it. Background technique [0002] Radio Frequency Identification (RFID) tags are composed of a radio frequency identification chip and a tag antenna. The antenna receives the radio communication signal of the radio frequency identification reader and transmits or updates the internal radio frequency identification chip. The recorded data or identification code. RFID tags have the advantages of fast reading speed, long reading distance, no need to read visually, and can read multiple at the same time without being affected by dirt. Therefore, in logistics management, access control, process tracking control... And so on, you can see the application of radio frequency identification technology. [0003] In the application of radio frequency identification technology, the design technology of the tag antenna is the key to the success...
