Cover Story: Our work presents a scalable and manufacturable approach for large-scale antenna arrays based on Goldberg polyhedra using hexagonal and pentagonal subarrays. This structure enables quasi-spherical, wide-angle digital beamforming with reduced distortion and improved sidelobe performance. The method simplifies fabrication through repeated planar subarrays while preserving high-precision beam steering, offering a feasible path toward industrial-scale radar and satellite antenna architectures.
