1. A wireless charging transmit end for wirelessly charging a receive end, comprising:
a signal processing apparatus; and
a dual-polarized antenna, wherein the dual-polarized antenna comprises at least one dual-polarized element;
wherein each dual-polarized element of the at least one dual-polarized element comprises a first linearly polarized element and a second linearly polarized element that are mutually orthogonal, wherein the first linearly polarized element is configured to receive a first wireless signal from the receive end, and wherein the second linearly polarized element is configured to receive a second wireless signal from the receive end;
wherein the signal processing apparatus is configured to:
obtain a first energy signal and a second energy signal based on a waveform relationship between the first wireless signal and the second wireless signal;
send the first energy signal to the first linearly polarized element; and
send the second energy signal to the second linearly polarized element;
wherein the first linearly polarized element is configured to transmit the first energy signal to the receive end and the second linearly polarized element is configured to transmit the second energy signal to the receive end such that the first energy signal and the second energy signal combine into an energy signal matching a polarized antenna of the receive end.
