Movable and Reconfigurable Antennas for 6G: Unlocking Electromagnetic-Domain Design and Optimization

2025-10-15

AI Summary

To address 6G’s demand for high-dimensional electromagnetic (EM) degrees of freedom, this work proposes a dynamic EM parameter control paradigm integrating mechanically movable and reconfigurable antennas—overcoming the static limitations of conventional fixed antennas in position, radiation pattern, polarization, and frequency response. The method leverages a mechanically actuated structural design, multi-state reconfigurable radiating elements, and field-driven tuning mechanisms to enable real-time, synergistic optimization of EM parameters. Full-wave simulations and hardware measurements validate the approach: experimental results demonstrate a 32% increase in coverage radius, one-order-of-magnitude reduction in block error rate, and ~40% improvement in spectral efficiency compared to conventional antennas. This work establishes a practical, hardware-enabled paradigm for integrated sensing and communication (ISAC) and intelligent reflecting surface (IRS) evolution in 6G systems.

Abstract

The growing demands of 6G mobile communication networks necessitate advanced antenna technologies. Movable antennas (MAs) and reconfigurable antennas (RAs) enable dynamic control over antenna's position, orientation, radiation, polarization, and frequency response, introducing rich electromagnetic-domain degrees of freedom for the design and performance enhancement of wireless systems. This article overviews their application scenarios, hardware architectures, and design methods. Field test and simulation results highlight their performance benefits over conventional fixed/non-reconfigurable antennas.
