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 prosed unit-cell has nearly constant performances regardless the polarization angle of the incoming waves. Then four resistive loads were embedded in the unit-cell to compute the radiation to RF conversion efficiency. An equivalent circuit model was also proposed and comparison was made to the simulation results.
