Abstract

This paper bridges the gap between holographic MIMO theory and practical implementation for 6G systems. We present a prototype holographic MIMO array with 1024 sub-wavelength antenna elements and demonstrate real-time beamforming at 28 GHz. The prototype achieves 256 simultaneous beams with 0.5-degree angular resolution, demonstrating the feasibility of holographic communication for next-generation wireless systems.
