A wideband electromagnetic rectification metasurface for collecting electromagnetic energy in the Wi-Fi frequency band is proposed in this paper. The size of the metasurface unit is 34 mm × 34 mm × 5 mm. The selected Schottky diode not only rectifies RF electromagnetic energy into DC energy but also utilizes its nonlinear and high-impedance characteristics in high-frequency circuits to achieve direct impedance matching between the spatial wave impedance and the metasurface, thereby increasing its operating bandwidth. Subsequently, the DC electromagnetic energy is delivered to the load through the filtering circuit on the back, enabling energy collection. The centrally symmetrical structure ensures that it can collect electromagnetic waves incident from any polarization direction in space, and its polarization insensitivity broadens its range of application.
