In this letter, a feasible three‐dimensional ultra‐broadband carpet cloak is presented. To realize the structure, use of multilayer dielectrics are proposed. The results prove that the three‐dimensional conducting bump can be concealed from all the viewing angles in an ultra‐broadband frequency range of 8–30 GHz. An experimental results confirm the performance of the proposed pyramidal cloak in practice. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1284–1288, 2017
