Fig. 4: Deformation correction validation.
Over-the-air measurement setup for deformation correction verification and radiation pattern. A Illustration of the test setup B Worst-case deformation with 38 cm radius of curvature by tiling four flexible 2 × 2 sub-arrays. C The stabilization loop reduces deformation error to <1.5∘ from 7∘; corresponding change in PS codes ϕ1, ϕ2, and ϕ3 are captured. D Test setup illustration for dynamic phase adjustment verification by moving the transmitter. E Dynamic phase adjustment validation when the transmitter moved from 0∘ to 15∘, and from 15∘ to 30∘.
