View original image[Asia Economy Reporter Oh Su-yeon] SK Telecom is leading the research and development of ultra-lightweight transparent antennas that can expand 5G and 4G (LTE) coverage simply by attaching them to glass windows.
On the 30th, SKT announced that through over three years of research collaboration with chemical materials company Dongwoo Fine-Chem, it has succeeded in developing transparent antenna equipment and RIS (Reconfigurable Intelligent Surface) technology. SKT has completed verification of core RIS technology that can enhance 5G and 4G (LTE) service quality through transparent antennas attachable to bus, subway, and building glass.
The newly developed technology involves attaching antennas with thin metal patterns in the form of small, lightweight transparent films to glass to receive radio waves. It can be installed so harmoniously with the surrounding environment that the antenna on the glass is hardly noticeable. By utilizing transparent antenna and RIS technology, wireless quality can be advanced and mobile communication service coverage can be expanded. Energy efficiency is also improved, reducing power consumption. It can also be used to reflect specific frequency bands to expand coverage inside buildings.
