Conductive film suitable for 5G communication. Ultrafine metal mesh is formed on transparent polymer materials. 

A transparent conductive film designed for 5G communication. The conductive film forms an ultra-fine wire diameter on a transparent polymer substrate, which has excellent transparency, flexibility and reliability, making the antenna layout more flexible. This feature makes it suitable for scenes with limited antenna installation space or high aesthetic requirements, such as ceilings, window glass, safety signs, large displays, etc.

New requirements for antenna installation in 5G era 

5G communication uses SUB-6G and millimeter-wave electromagnetic waves to achieve faster speed and greater data capacity. However, compared with LTE, high-frequency electromagnetic waves are easily blocked, which limits the antenna installation site. In order to ensure a reliable communication environment, the number and size of antennas need to be increased. 

In order to meet this demand, transparent flexible conductive film can be flexibly installed in mobile devices, IOT devices, display screens, walls, ceilings, window glasses, car windows and other locations to easily adapt to 5G electromagnetic wave transmission in various scenarios.

Application scenarios of transparent conductive film 

The transparent conductive film supports a variety of communication application scenarios including LTE, 5G, and WI-FI6. 

A : Indoor distributed antenna : vertical or parallel to the ceiling, covering more than 80 % of mobile data traffic 

B : Outdoor distributed antenna : Substitute for spotlight camouflage, lamp pole camouflage and other beautification antennas 

C : Support independent network : airport, factory, campus and so on.

The performance advantages of transparent conductive film 

The analysis data of the key properties of transparent conductive films show that the metal mesh is outstanding in many materials in terms of the requirements of 5G antennas for feeder and vibrator materials-low square resistance and high power tolerance adaptation, and good intermodulation suppression. 

Therefore, the transparent conductive film is made of metal mesh, and the precision etching of the large lift helps to achieve higher antenna gain and efficiency than other technical paths !
