The design, fabrication, and measurement of a novel and ultrathin metamaterial absorber are presented for X‐band. The absorber is constructed of a periodic array of new resonant structure with the thickness of 1/110 of the incidence wavelength. Simulation results show that the absorber can perform with an absorption peak of 100.00% at frequency of 10.116 GHz given a normally incident electromagnetic wave the full width at half maxima bandwidth is 5.057%. This absorber is polarization‐independent and wide‐angle incidence for both transverse magnetic and transverse electric polarizations. In addition, absorption spectrum curves were studied using the recursive method. To further enhance the absorption bandwidth of the novel design, the scalability property of metamaterials is utilized. Three and nine elements in one unit cell are arranged side by side in different scenarios, which have created double and triple‐band with full width at half maxima bandwidth of 10.552 and 17.084%, respectively. In all cases, the proposed structures are fabricated and experimental results show good agreement with the numerical simulation. © 2014 Wiley Periodicals, Inc.
