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

Radio frequency identification tags and label paper products using them. The present invention relates to a radio frequency identification label and a label paper product using the same. The radio frequency identification tag includes a signal source structure, a radiation structure, an isolation structure and a base material. The signal source structure includes a loop antenna and a radio frequency identification chip, and the radio frequency identification chip is electrically connected to the loop antenna. The radiating structure surrounds the signal source structure. The isolation structure is disposed on one side of the radiation structure at intervals. The substrate is used for carrying the signal source structure, the radiation structure and the isolation structure.

Description

technical field [0001] The present invention relates to a label, in particular to a radio frequency identification label and a label paper product using the same. Background technique [0002] The Radio Frequency Identification (RFID) tag is 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 inside of the radio frequency identification chip. The recorded data or identification code. RFID tags have the advantages of fast reading speed, long reading distance, no need for visual reading, and can read multiple at the same time without being affected by contamination. 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 RFID technology, the design technology of the tag antenna is the key to the ...
