Advanced and Sustainable Antenna Technologies for Sensing and Wireless Communications

Dear Colleagues,

The proliferation of next-generation wireless technologies such as 5G/B5G, the Internet of Things (IoT), and sensing applications has increased the demand for advanced antenna solutions and triggered the necessity of designs with sustainability in mind. To address these challenges, innovation is needed to develop materials and methodologies that, coupled with new designs, enhance antenna efficiency. This Special Issue focuses on the development and application of advanced and sustainable antenna technologies to shape the future of wireless communications and sensing technologies.

For this Special Issue, we seek to explore a diverse range of topics that concern advanced antenna technologies, suitable eco-friendly materials, and disruptive designs. We also welcome the integration of new and integrated technologies, machine learning (ML), and artificial intelligence (AI) to optimize antenna performance, including their placement for channel enhancement and beamforming networks. The use of ML has also gained great attention in the field of sensing, and therefore, we look forward to discovering the utilization of this integration in research.

Topics of interest for this Special Issue include, but are not limited to, the following:

• Green antenna technologies: Sustainable materials and energy-efficient designs.
• AI- and ML-driven antenna optimization: Enhancing performance and adaptability using data-driven methods.
• AI- and ML-driven sensing/imaging techniques: Enhancing characterization and classification accuracy and speed.
• Reconfigurable and intelligent antennas: Systems capable of real-time adjustments for enhanced efficiency.
• Next-generation wireless communication systems: Antennas designed for 5G, 6G, and IoT applications.
• Satellite antennas: Antennas for satellite communications and remote sensing satellites.
• Wearable and flexible antennas: Innovations for healthcare, consumer electronics, and industrial applications.
• Metamaterial and holographic antennas: Advanced solutions for improved bandwidth and signal integrity.
• Integrated sensing and communication (ISAC): Dual-purpose antennas for simultaneous communication and environmental sensing.
• Antennas for sensing applications: Novel designs to improve the sensitivity and reliability of environmental sensing.
• Energy harvesting and self-powered antennas: Systems designed to operate autonomously through ambient energy sources.
• Wide-angle scanning arrays and full-duplex systems: Advanced arrays and antennas for high-capacity, low-latency communication.
