6G, AI antennas, Beam steering, Frequency tuning, Machine learning, Reconfigurable antennas, THz communicationAbstract
The advent of sixth-generation (6G) wireless networks marks a paradigm shift toward ultra-high data rates, seamless connectivity, and near-zero latency. Achieving these targets requires efficient operation in millimeter-wave (mmWave) and terahertz (THz) bands, where severe propagation losses, spectrum scarcity, and hardware constraints impose unprecedented challenges on antenna systems. Reconfigurable antennas (RAs) have emerged as a pivotal solution, offering the ability to dynamically adapt frequency, polarization, and radiation characteristics to ensure robust performance in highly variable environments. In parallel, artificial intelligence (AI) and machine learning (ML) are playing a transformative role in antenna design, optimization, and control. By leveraging algorithms such as deep reinforcement learning and convolutional neural networks, AI enables autonomous beam steering, adaptive resource allocation, and fault detection, and predictive optimization capabilities essential for 6G adaptability. Integrating AI with RA architectures enhances spectral efficiency, energy utilization, and network resilience, while reducing hardware redundancy. Recent advances demonstrate significant performance gains, including improved impedance matching, expanded bandwidth, and real-time beam reconfiguration. This synergy between AI and reconfigurable antenna technology not only addresses the stringent requirements of 6G communication systems but also lays the foundation for scalable, intelligent, and self-optimizing networks. Ultimately, AI-optimized RAs represent a transformative pathway for ensuring efficiency, reliability, and sustainability in next-generation wireless infrastructures.
