Verbundprojekt: Intelligente Hochfrequenz-Antennen für energieeffiziente Kommunikationsanwendungen - GLEMORIS -

This project focuses on developing a novel low-power Reconfigurable Intelligent Surface (RIS) panel using ultra-low-power RF CMOS switch chips and embedded decoders as phase shifters to meet the demands of 6G wireless networks. The goal is to reduce energy consumption while maintaining high performance, enabling more efficient signal control in next-generation communication systems. The collaboration involves National Chung Cheng University (CCU) in Taiwan and Fraunhofer Institutes IPMS and HHI in Germany, with each partner contributing their expertise. Key tasks include designing low-power CMOS switches for RIS, integrating these switches into RIS elements, and conducting system-level testing to evaluate performance in real-world deployment scenarios. The project will also feature student exchanges and continuous collaboration between Taiwan and Germany. The goal of developing CMOS-based low-power RIS will be demonstrated with a 15 GHz 32x32 RIS panel with gain of 55 dB, reflection beamwidth of 4o, RF power consumption less than 1 W, and RF switching time less than 1µs and digital control time less than 1 ms. The work is structured into several phases: concept development, IC design, RIS integration, and system testing. Fraunhofer IPMS will lead the design of the low-power ICs, CCU will integrate the ICs into RIS elements, and Fraunhofer HHI will oversee system-level testing, including over-the-air measurements and performance evaluations. By combining the strengths of each partner, the project aims to advance RIS technology, contributing to the development of energy-efficient, high-performance 6G networks. This collaboration promotes cross-border knowledge exchange and aims to establish cutting-edge solutions for sustainable and advanced communication technologies.
