Abstract:
The upcoming sixth-generation (6G) wireless networks are expected to deliver extremely high capacity, reliability, massive connectivity, and services that extend beyond traditional communications. In response to these demands, the fluid antenna system (FAS)—encompassing software-controllable fluidic, dielectric, or conductive antenna structures such as liquid-based antennas, RF pixel antennas, movable antennas, and metasurfaces—has emerged as a promising technology for flexible and adaptive wireless communications. Unlike conventional antenna systems that rely on multiple fixed-position antennas with discrete spacing, FAS offers very fine spatial resolution and dynamic reconfigurability in shape, size, position, and orientation, enabling it to fully exploit spatial variations and achieve significantly enhanced performance. Recent studies reveal strong connections between FAS, holographic MIMO systems, and reconfigurable intelligent surfaces (RIS), allowing cross-fertilization of concepts to accelerate advances across these technologies. In addition, FAS introduces new capabilities for multiuser communication by leveraging spatial opportunities where interference experiences deep fades, giving rise to novel forms of multiple access. Motivated by the rapid growth of research activity and emerging opportunities in this area, the proposed tutorial, “Fluid Antenna System (FAS): Fundamentals and Recent Advances,” aims to bring together academic and industry researchers to present the latest developments and explore future research directions in this evolving field.
