Abstract: Visible light communication (VLC) is a key technology for advancing 6G networks.However, achieving both high signal gain and a wide field of view (FOV) at the receiver remains a significant challenge.To address this, we design a patterned fluorescent antenna (PFA) with microstructures fabricated via nanoimprinting technology.The microstructures modify the optical signal propagation within the fluorescent antenna, thereby enhancing its light transmission efficiency.Experimental results demonstrate that the patterned fluorescent antenna not only maintains a wide receiver FOV but also achieves high signal gain.Specifically, within the incident angle range of 0° to 60°, the average signal gains achieved by the single-sided and double-sided PFAs are 4.34 and 6.19 dB, respectively.This study provides an effective solution for enhancing signal gain in VLC systems under a wide FOV condition.
