What is the effect of ferrite absorber?

Author:admin   AddTime:2021-09-18

In handheld devices such as NFC payment mobile phones, electronic tags must be integrated or attached to the electronic device. In this way, the alternating electromagnetic field induced by the tag under the action of the signal from the card reader is easily attenuated by the metal eddy current. The signal strength is greatly reduced, causing the reading process to fail. Therefore, in order for the product to be able to better use the card reader, it is necessary to add a microwave absorbing material to the product.



The ferrite absorber is made by ceramic technology, the texture is relatively hard, and it is also a brittle material. It has a higher magnetic permeability at high frequencies. In RFID/NFC applications, use its high permeability and low loss characteristics; when using, insert the ferrite absorbing material between the 13.56MHz loop antenna and the metal (PCB board or battery) to increase the induced magnetic field Through the absorbing material itself, the probability of passing through the metal is reduced, thereby reducing the induced eddy current in the metal plate, thereby reducing the loss of the induced magnetic field. At the same time, due to the insertion of the ferrite absorbing material, the measured parasitic capacitance will also be reduced. , The frequency deviation is reduced, consistent with the resonant frequency of the card reader, thereby improving the reading distance. Of course, the degree of improvement depends on the excellent degree of the characteristics of the absorbing material.
