A Framework for Array Shape Reconstruction Through Mutual Coupling

Flexible phased arrays potentially enable diverse applications not permitted by rigid systems; however, they introduce ambiguity in antenna element positions. If this position can be overcome, flexible perform the full suite of array functions: beam steering, wavefront engineering, and focusing. Furthermore, shape reconstructions used for beyond beamforming. We propose a framework to reconstruct that only uses mutual coupling measurements does require additional sensors or functionalities system. discuss approach, two-step algorithm, which is highly modular implemented variety systems. To demonstrate accuracy we present results from two passive 2.5-GHz setups using dipole patch antennas, as well 10-GHz (active) integrated circuit array, approach In all cases, algorithm reconstructs accurately, with average errors approximately 6% wavelength. This article serve beginning broad study reconstruction algorithms their applications.
