Anti metal high-frequency electronic tags are electronic tags that use new materials with anti-interference functions, which effectively solves the problem of metal carriers interfering with the RF signals of electronic tags attached to their surfaces.

 

In ultra-high frequency (UHF) RFID tag systems, the identification of tags affixed to metal carriers is particularly difficult. These systems provide a large read/write range, but their RF is more difficult to penetrate obstacles such as metals. Higher frequency radio waves will be reflected back by metal objects.

Currently, high-efficiency wave absorbing materials are used, based on the principle of electromagnetic waves propagating in the medium from a low magnetic conductivity to a high magnetic conductivity direction. High permeability ferrite is used to guide electromagnetic waves. Through resonance, a large amount of radiation energy of electromagnetic waves is absorbed, and then the energy of electromagnetic waves is converted into thermal energy through coupling.

RFID anti metal tags are divided into high-frequency and ultra-high-frequency tags. Anti metal tags also include flexible anti metal tags, PCB anti metal tags, ceramic anti metal tags, ABS anti metal tags, and anti-metal mobile phones.

    The anti removable ceramic RFID electronic tag uses a composite ceramic substrate inside, which is resistant to high temperature and has stable performance. Ceramic labels are inherently fragile, making them highly suitable for applications that prevent disassembly and tearing. The combination of anti disassembly ceramic labels with automotive glass can achieve excellent readability performance.
