The application of ferrite is mainly to use the high magnetic field characteristics of a type of high magnetic field rate, low loss type wave absorbing material; when using, insert the wave absorber between the 13.56MHz loop antenna and the metal substrate to increase the induced magnetic field through the absorption The wave material itself reduces the chance of passing through the metal plate, so as to reduce the induced eddy current in the metal plate, thereby reducing the loss of the induced magnetic field. At the same time, because of the insertion of the wave absorber, the measured parasitic capacitance will also be reduced, and the frequency offset The reduction is consistent with the resonant frequency of the card reader, thereby improving the reading distance. Of course, the degree of improvement depends on the goodness of the characteristics of the absorbing material.

Electromagnetic shielding material is a functional composite material that mainly absorbs electromagnetic waves, eliminates the back and forth reflection of electromagnetic waves in the shielding cavity, reduces the interference of clutter to its own equipment, enhances the magnetic conduction effect, improves the magnetic field strength, and effectively increases the sensing distance. At the same time, it also effectively prevents electromagnetic radiation from interfering and harming surrounding equipment and personnel.



In NFC payment mobile phones and other handheld devices, the electronic tag should be integrated or attached to the electronic device, and function as a part of the device. It is applied to the NFC payment mobile phone antenna to isolate the metal conductor's absorption and attenuation of the antenna magnetic field, which can effectively Improve the performance of the antenna, increase the magnetic field strength of the antenna, and increase the sensing distance and sensitivity of the NFC antenna.

Product performance:
Effectively improve the performance of NFC products, easy to use, can be bent at will, bring your own
Double-sided tape enhances the fit of the combined body, which can be stamped according to the requirements of use
Increasing the magnetic field strength of the antenna effectively increases the sensing distance while ensuring low magnetic loss.

Applied to:
NFC-enabled mobile phones, non-contact IC cards, RFID readers/writers/RFID tags NFC mobile phone antennas and RFID devices/tags, isolation metal materials absorb the antenna magnetic field, increase the antenna's magnetic field strength, and effectively increase the communication sensing distance.
