Product Description
Wave-absorbing material in RFID anti-metal label applicationAfter more than ten years of development in China's RFID industry, now the technology has been relatively mature, especially in the past two years, under the background of the country actively encouraging and vigorously promoting the healthy development of the industry, with the continuous promotion of the Internet of Things, it has maintained a steady rising development trend.The industry has also reached a consensus on the frequency standard formulation of RFID.At present, the international frequency of 13.56MHz,13.56MHz high-frequency RFID technology has a stable performance and reasonable price, matching its reading distance range and practical application distance range, so it is widely used in bus card and mobile phone payment.The RFID electronic tag is used under the 13.56MHz, which usually has a maximum read and write distance of about 10 cm, and the chip's current consumption is about 1 mah.Because as the frequency increases, the inductance of the required electronic tag coil shows a decrease in the number of coil turns, usually where the typical number of turns is 3 to 10 turns.The RFID tag-reading card distance is not only related to itself, but also has a lot to do with its environment.When using inductively coupled RFID systems, it is often required that a reader or electronic tag antenna be mounted directly on a metal surface.However, it is not possible to install a magnetic antenna directly on a metal surface.RFID electronic label is often used in metal environment. When RFID electronic label is close to metal, because the metal is strongly reflective to electromagnetic waves, so it will be accompanied by the signal weakening, the card distance will become closer, serious interference will appear card failure phenomenon.The current common solution is to put a layer of wave-absorbing material on the back of the electronic label.Application of ferrite in NFC coils or antenna platesUltra-thin sintering NFC ferrite sheet brief introduction: 13.56MHZ antenna ferrite sheet / film is a high temperature sintering ferric oxide material.In handheld devices such as payment mobile phones, the main function of electronic labels is to reduce the absorption of the signal magnetic field, and the ferrite film itself is a high-temperature sintering ferrite material, which effectively increases the induction distance by increasing the magnetic field strength.1. Effect of ultra-thin sintering NFC ferrite tablets:Near-field communication, Near Field Communication (abbreviated as NFC) technology has attracted wide attention with its advantages of high transmission bandwidth, high security and low energy consumption.At present, the mobile phone one-card based on this technology has begun to emerge, and the use of NFC mobile phone to open the door, parking, mobile payment and other ways has become a new fashion of consumption.2. Application field of ultra-thin sintering NFC ferrite tablets:In terms of efficacy, ferrite magnetic sheet is mainly used to prevent NFC communication signal from being absorbed by metal, battery; increase the magnetic field strength of antenna and effectively increase the communication sensing distance.In terms of product quality assurance, the perfect material control and quality system make its product performance reach the level of the same series of products in Japan and South Korea, and fully meet the NFC communication distance requirements.sum up:Ferriite film: effectively improve the performance of NFC antenna products can bend by increasing the magnetic field intensity of the antenna, effectively increase the induction distance;Main application of ferrite tablet: NFC function of mobile phone non-contact IC card RFID read / writer / RFID tag. What is absorbing materials?
1.All the items possess the function of magnetic. By attached between the antenna and the back metal, forming a magnetic conduction channel, which can eliminate the interfere to antenna from metal (Or other sources of interference) , Enable the antenna to transmit a signal normally.2.The main ingredient is compounded of the various types of wave absorbing powder and polymer resin composite. Our product is high loss and excellent impedance, applied to suppress the electronic noise from different frequency electromagnetic. After the electromagnetic wave be injected into the interior of the absorbing material, by the hysteresis loss, dielectric loss, resistance loss, eddy current loss, interference reduction mechanism is changed into heat energy, energy and other forms of energy, to achieve the effect of absorbing electromagnetic wave . There are parts of items holds the dual characteristics of absorbing and shielding electromagnetic wave, the effect is rather excellent in certain applications. 3.
