Abstract: A power supply end, a wireless power supply system, a power supply method, and a computer storage medium, to improve wireless power supply efficiency. The power supply end includes a transceiver and a plurality of radiation circuits. The transceiver is configured to: generate a charging signal including an electromagnetic wave of at least one frequency band, and separately provide the charging signal for the plurality of radiation circuits. Each of the plurality of radiation circuits can transmit an electromagnetic wave of one or more target frequency bands. The plurality of radiation circuits include a first radiation circuit and a second radiation circuit. One or more target frequency bands included in an electromagnetic wave transmitted by the first radiation circuit are different from one or more target frequency bands included in an electromagnetic wave transmitted by the second radiation circuit.

Abstract: A wireless charging transmit end is provided in this application, which includes a dual-polarized antenna which includes at least one dual-polarized element and a signal processing apparatus. Each dual-polarized element includes a first linearly polarized element and a second linearly polarized element that are mutually orthogonal and 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. The first energy signal is sent to the receive end by the first linearly polarized element, and the second energy signal is sent to the receive end by the second linearly polarized element. The first energy signal and the second energy signal are combined into an energy signal matching the receive end.
