A curved metasurface radome is designed to extend the scanning angle of a phased‐array antenna. Unlike the previous method, using negative index materials or transformation media (inhomogeneous and anisotropic), herein, only ordinary natural materials, i.e., a single‐layer well‐arranged ceramic block, are used, to realize the functions of the angle extending effect. The designed radome has a smaller size, lighter weight, a large angle extending effect, and is easy for fabrication. Therefore, the proposed method is more likely to be used in practical applications. The performance of the radome is verified by both numerical simulations and experimental demonstrations.
