Abstract
An RF energy harvesting system includes an antenna, an impedance matching network, an RF rectifier module, an enhanced RF rectifier module, a protection circuit, a power control module, an energy storage branch and load branches. The antenna receives RF signals and converts the RF signals into electric energy. The impedance matching network produces an initial voltage signal according to the electric energy output by the antenna. The RF rectifier module converts the initial voltage signal into a first voltage signal. The enhanced RF rectifier module converts the initial voltage signal into a second voltage signal. The power control module is self-driven through the first voltage signal and the second voltage signal. The RF rectifier module adjusts the internal electrical connection according to control signals of the power control module. The energy storage branch stores the electric energy output by the power control module.
