In this paper, two kinds of ring-type microwave electric resonant structures were proposed, which were appropriately assembled with metal wires to form electromagnetic coupling units. The coupled structures have resonance response to the incident electromagnetic wave, and absorb the electric and magnetic fields strongly. We simulated these two kinds of coupled structures, and then optimized the simulation results to achieve the best absorption properties. The electromagnetic properties (the reflection coefficients S11 and the transmission coefficients S21) of metamaterial absorber sample were measured using free space method in microwave frequency from 8 to 12 GHz. At 10.7 GHz and 10.07 GHz, the absorptivity reaches 95% and 98%, respectively.
