Fluid antenna systems with continuously optimized positions achieve linear DOF growth with aperture size D/λ and O(1/D^{2L}) CRB scaling for L sources, outperforming grid-constrained designs via a two-stage FAS-MUSIC algorithm.
A fluid-antenna hybrid architecture for DOA estimation achieves near fully-digital accuracy while cutting RF hardware complexity and training overhead in 6G networks.
