The disclosure provides a wireless charging device including a metal frequency-selective box and an internal charging system disposed inside the metal frequency-selective box for wireless charging. The internal charging system includes a multi-antenna subsystem including N antenna units; N is an integer greater than 2, and the antenna units are dipole antennas, microstrip patch antennas, microstrip slot antennas, helical antennas, or dielectric resonator antennas. The N antenna units are evenly disposed, in a two-dimensional ring, on inner sides of four side faces of the metal frequency-selective box, or disposed on a three-dimensional curved surface of the entire inner side of the metal frequency-selective box. The device to be energized is disposed in the metal frequency-selective box and is surrounded by the N antenna units.
