Abstract
A wireless charging device includes a wireless charging transmitter transmitting a charging signal to a signal gain module to generate at least one gain signal. The signal gain module includes an insulation substrate with an upper surface thereof provided with a first conductive wire. The first conductive wire makes at least one turns arranged along the inner edge of the insulation substrate. The lower surface of the insulation substrate is provided with a second conductive wire whose position corresponds to the position of the first conductive wire. A connecting element is arranged between the first conductive wire and the second conductive wire, such that the first conductive wire is electrically connected to the second conductive wire through the connecting element. The present invention provides a charging signal with high intensity to avoid the low charging efficiency caused by deflection and too long a distance.
