Invisible Connectivity: Transparent Antennas for the Future of Smart Cities

Overview

This project focuses on advancing optically transparent antenna (OTA) technologies to support the dense wireless infrastructure required for future smart cities. As 5G deployment expands and 6G emerges, integrating wireless hardware into modern urban environments—such as glass façades, vehicle windows, and digital displays—has become increasingly challenging. The project proposes combining next-generation transparent conductive materials with AI-driven antenna design to create high-performance, visually unobtrusive antennas.

Using artificial intelligence, novel mesh geometries, including fractal and hybrid designs, will be generated to optimize the trade-off between optical transparency and electromagnetic performance. The research will leverage advanced materials such as graphene, transparent conductive oxides, and XPANCEO’s ultra-thin 2D gold films, while also exploring reconfigurable antenna concepts enabled by gold–graphene composites. Through simulation, prototyping, and experimental validation, the project aims to deliver transparent antenna prototypes and a library of AI-optimized design templates suitable for smart city wireless infrastructure.
