Breaking through metal interference and improving RFID recognition rate -1GHz~20GHz non-woven absorbing material

In modern society, the application of RFID technology is becoming increasingly widespread. However, metal interference has always been the main issue affecting the stability and recognition rate of RFID systems. To solve this problem, a new type of 1GHz to 20GHz non-woven absorbing material has emerged. This article will provide a detailed introduction to the characteristics, scope of use, and important role of this material in RFID systems.

1. Strong anti-interference ability: Non woven absorbing materials can effectively solve metal interference in LF/HF RFID systems. Whether on metal surfaces or batteries, non-woven absorbing materials can eliminate losses caused by eddy currents and effectively isolate magnetic fields, ensuring stable transmission of card reading signals.

2. Improve communication distance: The tag antenna made of this material has good resistance to metal interference, which can increase communication distance and overcome the limitation of metal interference on the communication distance of RFID systems. In addition, the material can also be used to solve the interference problem at frequencies of 13.56MHz and 125KHz, further improving the radio frequency identification rate.

3. Multiple practical specifications: This non-woven absorbing material can be cut into different sizes according to needs. The commonly used specifications are A4 size, 297 millimeters long and 210 millimeters wide. In terms of thickness, there are multiple options available for creators to adjust according to actual needs. The commonly used standard thickness is 0.12-0.14 millimeters, with a thickness range of 0.1-0.25 millimeters.

4. Convenient usage: The commonly used shape of non-woven absorbing materials is sheet, which makes the application of materials more flexible and convenient. In addition, according to different needs, the material can be single-sided with double-sided tape or without double-sided tape to meet the requirements of different occasions and usage environments.

5. Reliable working performance: This material can perform well at different temperatures, with a working temperature range of -30 ℃~85 ℃, and can adapt to various environmental conditions.

Conclusion: In the era of intelligent commercial big data, the application of RFID technology is ubiquitous. However, the issue of metal interference has always limited its further development and application. The emergence of 1GHz to 20GHz non-woven absorbing materials provides a scientifically feasible solution to the problem of metal interference. It not only effectively isolates metal interference, improves communication distance and RFID recognition rate, but also has diverse specifications, convenient use, and reliable performance. I believe that with the further development and promotion of technology, this material will inject new impetus into the development of RFID technology.
