WIRELESS CHARGING TRANSMIT END, METHOD, AND SYSTEM

This application discloses a wireless charging transmit end, a method, and a system. The transmit end includes a signal processing apparatus and a dual-polarized antenna. The dual-polarized antenna includes at least one dual-polarized element. Each dual-polarized element includes a first linearly polarized element and a second linearly polarized element that are mutually orthogonal. The first linearly polarized element and the second linearly polarized element respectively receive a first wireless signal and a second wireless signal from the receive end. The signal processing apparatus obtains a first energy signal and a second energy signal based on a waveform relationship between the first wireless signal and the second wireless signal, sends the first energy signal to the first linearly polarized element, and sends the second energy signal to the second linearly polarized element. The first linearly polarized element transmits the first energy signal to the receive end. The second linearly polarized element transmits the second energy signal to the receive end. The first energy signal and the second energy signal are combined into an energy signal matching the receive end. The combined energy signal can match an antenna of any polarization type. This improves energy transmission efficiency.
