Special Issue Information

Dear Colleagues,

Futuristic antenna designs are necessary to meet the demands of rapidly evolving technologies and next-generation wireless communication systems. These designs address current challenges and enable capabilities required for driving technological advancements. Therefore, this Special Issue focuses on the innovative and futuristic antenna designs and implementations that drive the evolution of wireless communication systems, including 5G, 6G, and beyond. It explores emerging innovations that advance the frontiers of sustainable, efficient, reconfigurable, and adaptable antenna designs with not only using classical strategies, but also using the unconventional and modern strategies including artificial intelligence. This Special Issue covers a broad spectrum of topics regarding futuristic antenna technologies. Topics include, but are not limited to, the following:

  • Unconventional antenna design;
  • Sustainable antenna materials and design;
  • Energy-efficient antenna system and design;
  • Reconfigurable, scalable, and adaptive antenna system and design;
  • AI and machine learning in antenna design;
  • Wide-angle scanning array (WASA);
  • Full duplex antennas (FDA);
  • Antennas for automotive radars;
  • Antennas for high-frequency applications;
  • Holographic and metamaterial-based antennas;
  • Substrate-insensitive patch antenna;
  • Flexible and wearable antennas;
  • Plasma antennas;
  • Fluid antennas;
  • Integrated sensing and communication (ISAC);
  • Smart electromagnetic environments (SEMEs).

The purpose of this Special Issue is to bridge the gap between innovative antenna designs and their practical application in real-world, sustainable communication systems. This Special Issue aspires to serve as a platform for groundbreaking research and collaboration, shaping the future of wireless communications with antennas that are not only advanced, but also responsible and forward-thinking.

Fluid Antenna Systems (FASs) have recently emerged as a promising solution to address the demanding performance indicators (KPIs) and scalability challenges of future 6G mobile communications. By enabling agile control over both radiating position and antenna shape, FAS can significantly improve diversity gain and reduce outage probability through dynamic selection of the optimal radiation point, also known as port. Numerous theoretical studies have explored novel FAS concepts, often in conjunction with other wireless communication technologies such as multiple-input multiple-output (MIMO), Non-Orthogonal Multiple Access (NOMA), Reconfigurable Intelligent Surfaces (RIS), Integrated Sensing and Communication (ISAC), backscatter communication, and Semantic communication. To validate these theoretical concepts, several early-stage FAS hardware prototypes have been developed, including liquid–metal fluid antennas, mechanically movable antennas, pixel-reconfigurable antennas, and meta-fluid antennas. Initial measurements have demonstrated the potential advantages of FAS. This article provides a brief review of these early FAS hardware technologies. Furthermore, we share our vision for future hardware development and the corresponding challenges, aiming to fully release the potential of FAS and stimulate further research and development within the antenna research community.
