First Claim
1. A wireless charging device for wirelessly transmitting electric power to an electronic device, the wireless charging device comprising:
- a housing;
a shield-can provided within the housing, with a separation distance between a top of the housing and a top of the shield-can;
a system board provided within the housing and comprising a power amplifier;
a transmission resonator provided between the top of the housing and the top of the shield-can and configured to simultaneously generate a vertical magnetic field and a horizontal magnetic field; and
a metal sheet provided between the shield-can and the transmission resonator and configured to control at least one from among an intensity and a direction of at least one from among the vertical magnetic field and the horizontal magnetic field,wherein the transmission resonator is positioned in a horizontal direction within the housing, with respect to the top of the housing,the separation distance comprises a first separation distance between the top of the shield-can and the metal sheet, a second separation distance between the metal sheet and the transmission resonator, and a third separation distance between the transmission resonator and the top of the housing, andthe at least one from among the intensity and the direction of the at least one from among the vertical magnetic field and the horizontal magnetic field is changed by varying at least one from among the first separation distance, the second separation distance, and the third separation distance.
