SEKISUI CHEMICAL Develops Transparent and Flexible Radio Wave Reflection Film for 5G Communications

TOKYO, Jan. 5, 2022 /CNW/ — SEKISUI CHEMICAL CO., LTD. (hereinafter “SEKISUI”) is pleased to announce that its High Performance Plastics Company has developed a transparent and flexible type of radio wave reflection film for 5G communications by combining SEKISUI’s distinguished film and optical adhesive technologies with the metamaterial technology of Meta Materials Inc. headquartered in Canada.

SEKISUI verified the radio wave environment of the film with collaboration from DOCOMO Innovations, Inc. headquartered in the U.S. and confirmed that the product, having unprecedentedly high transparency and radio wave diffusion characteristics, provides wide frequency coverage useful for 5G and 6G communications.

1. Background of the development

In 5G and 6G radio wave communications, higher frequency ranges than conventional LTE (4G) services are used: Sub-6 (3.6 GHz or higher) and millimeter (24 GHz or higher) wave ranges. Millimeter waves feature a high transmission capacity but have strong directivity; when reaching a shielding object such as a building, they attenuate, deteriorating communications quality. Installing a base station or relay station may resolve the deterioration, but such a solution involves a high additional investment, and a more reasonable cost solution was demanded.

While millimeter wave reflection plates, which have a metamaterial copper pattern processed on the printed circuit board, have been developed as a possible measure for solving such a challenge, SEKISUI directed attention to transparent and flexible radio wave reflection film that would have a metamaterial structure and would not spoil the landscape. Believing that it would be able to provide a solution by incorporating its film and optical adhesive material technologies …
