Teijin has developed a transparent polycarbonate with excellent dielectric properties for use in devices compatible with high frequency bands.

5G and 6G communications require signal transmission in high frequency bands. Furthermore, low dielectric (Low-K) properties are required to reduce signal attenuation and achieve efficient communication. On the other hand, in high frequency bands, the propagation distance of radio waves is shorter, so more antennas need to be installed. There is now a growing demand for communication equipment that do not spoil the scenery and design.
Teijin‘s newly developed transparent, low dielectric polycarbonate has superior dielectric properties compared to conventional polycarbonates and is maintain transparency. It is ideal for applications requiring transparency such as antennas, displays, and vehicle antennas. This film-formed material not only offers beautiful designs and an appearance that blends in with the environment, but also provides excellent workability thanks to its flexibility and ability to a variety of shapes, and its low dielectric properties minimize loss in radio wave propagation.　Transparent film antennas are expected to play a key role in the deployment of next-generation communication technologies such as 5G and 6G in urban and complex environments due to their efficiency and functionality.
