Antenna ferrite sheet/film

Provide products according to customer requirements

13.56MHZ antenna ferrite sheet/film is a high-temperature sintered ferrite material bai.
In NFC (Near Field Communication) payment mobile phones and other handheld devices, the main function of the electronic tag is to reduce the absorption of the signal magnetic field by the metal material. At the same time, the ferrite film itself is a high-temperature sintered ferrite material. The strength of the magnetic field effectively increases the sensing distance. The payment method of the mobile phone (NFC) is realized through the 13.56MHz RFID radio frequency identification system. The RFID smart label of this application is affixed to the back cover of the mobile phone, which can save space to the greatest extent. In handheld electronic devices such as mobile phones, electronic tags need to be integrated or attached to the electronic device and function as a component of the device. Often due to limited space, it is inevitable to attach RFID tags (usually passive) to metals, etc. The surface of conductive objects or the place where there are metal devices nearby. In this way, the alternating electromagnetic field induced by the tag under the action of the signal from the reader is easily attenuated by the eddy current of the metal, which greatly weakens the signal strength, 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 absorbing materials to the product. Ferrite sheets have begun to be widely used in the field of micropayment mobile phones and radio frequency.
