Professor Yingjie Jay Guo identifies analogue multibeam antennas and metasurfaces as critical breakthroughs for 6G, offering a low-energy, low-cost alternative to power-hungry digital beamforming in multiuser systems. His research highlights the Generalised Joined Coupler (GJC) matrix, a novel RF feed network that enables independently steerable beams and reconfigurable hardware to support intelligent, software-defined networks. These innovations are essential for integrating sensing and communications (ISAC) while addressing challenges in environmental propagation and system complexity. Ultimately, Guo emphasizes that future 6G success relies on combining hardware reconfigurability with AI, alongside increased international collaboration to accelerate talent development.
