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.
