In the present work, a microstrip resonator metamaterial absorber was designed and simulated using Computer Simulation Technology Microwave Studio (CST MWS). Annealed copper is chosen for the microstrip structure and FR-4 as a substrate. The 0.8 mm FR-4 is chosen for light weight, flexibility and for the absorption of Electromagnetic Waves. S-parameters at the input port indicated a reduction in the received signal level. The values of S-parameters obtained are less than -24 db at resonance frequency of 10.648 GHz having bandwidth of 152 MHz at -10 db. The S-parameters at various incidence angles showed that increasing the incidence angle resulted in decreased electromagnetic wave absorption. The results demonstrate that the metamaterial absorber provides effective electromagnetic shielding capabilities in the X band.
