In this paper, we demonstrate the feasibility of harvesting electromagnetic waves by using a metamaterial absorber unit-cell with a high absorption rate of 98.86 %, that operates at 5.8 GHz. The numerical results show that the proposed unit-cell has nearly constant performances regardless the polarization angle of the incoming waves. Then four resistive loads were embedded in the unitcell to compute the radiation to RF conversion efficiency. An equivalent circuit model was also proposed and comparison was made to the simulation results.
