RF ENERGY TRANSMITTING APPARATUS, RF ENERGY HARVESTING APPARATUS AND METHOD OF RF ENERGY TRANSMITTING

摘要

An RF energy transmitting apparatus is applied to an RF energy harvesting apparatus, the RF energy transmitting apparatus includes: a power radar transmitter receiving a power source signal and emits an electromagnetic source wave. A radar controller is electrically connected to the power radar transmitter and receives a reflected harmonic wave. After receiving the electromagnetic source wave, the RF energy harvesting apparatus generates and emits the reflected harmonic wave. After the radar controller receives the reflected harmonic wave, the radar controller determines a polarization angle of a reflection signal from the RF energy harvesting apparatus, and the radar controller adjusts the polarization angle of the antenna of the power radar transmitter to be within a predetermined range around the polarization angle of the reflected harmonic signal from the RF energy harvesting apparatus for an optimal received power.
