Abstract
This paper presents a dual-band and polarization-independent metasurface with wide range of incident angle for harvesting ambient electromagnetic energy. The proposed unit structure consists of a centrosymmetric metal closed-ring cross, F4B substrate, and 4 loads connected to the ground through 4 metal vias. The fully centrosymmetric structure keeps the working performances of the proposed metasurface unchanged under different polarization directions. Simulation results show that more than 80% of the energy at 2.45GHz and 5.8GHz can be captured at any incident angle ranging from 0°to 60°, taking into account the slight offset of the resonant frequency (no more than 0.05GHz).
