Numerical and experimental generated data during project https://doi.org/10.1109/ACCESS.2025.3633806

The dataset was generated during a project aimed at developing a low-profile, single-layer printed metasurface for near-field phase correction in aperture-based antennas to enhance far-field radiation performance. A novel unit cell design is introduced for the phase-correcting metasurface with significantly reduced thickness. Each unit cell consists of a single-layer dielectric substrate with a metallic square loop at the center, surrounded by four L-shaped patches at the corners, printed on both the top and bottom surfaces. The printed metasurface is designed based on the principle of near-field phase transformation. Compared with existing multilayer metallic or printed phase-correcting metasurfaces, the proposed single-layer design significantly reduces the profile, fabrication complexity, weight, and cost while providing improved performance.
