N2 - In this paper, an ultrathin Swastik shape unit cell structure of a metamaterial absorber (MA) is capable of increasing absorption in the X-band spectrum for a variety of applications. The structure of the MA is arranged periodically and has a swastika shape with lumped resistor resonator. In addition to having an intuitive design, the unit cell structure is able to absorb more than 80% of the desired band. The simulated result shows two absorption peaks at 5.05 and 12.60 GHz with more than 95% absorptivity. A proposed absorber provides absorption bandwidths between 4.19 and 13.33 GHz (9.14 GHz) in Full-Width Half Maxima (FWHM). An ultrathin absorber has a thickness of 0.035 mm, which is nearly λ/10 corresponding to the absorption central frequency of 8.67 GHz. The unit cell’s size of MA is 9 × 9 mm2, with a thickness of 3.2 mm (0.0346 λ).
