Abstract
A transparent frequency selective surface (FSS) on a glass window is proposed for signal selectivity of 5G millimeter-wave communication, based on a transparent and low loss material cyclic olefin copolymer (COC). The proposed FSS based on dual-loop units is designed on both sides of COC, which helps to realize the band-pass filtering effect under both normal and oblique-incident conditions in the desired frequency range from 27.5 to 29.5 GHz. The metal-meshed technology is employed to enhance the light transmission of the circuits, and the measured performances with traditional glass show that our proposed concepts can be a potential solution for signal filtering at millimeter wave on glass windows.
