Abstract: The present invention provides a mobile terminal which, when wireless (contactless) charging of a battery is performed by approximating a transmission coil of a charging unit (charging pad) and a reception coil provided in a wireless charging module of a mobile terminal, can adjust the saturation magnetic flux density and eddy currents of a shield sheet to which the reception coil is attached, the shield sheet being provided in the wireless charging module. When the reception coil is placed on the shield sheet to perform wireless charging, the saturation magnetic flux density and eddy current generation in the shield sheet are adjusted for wireless charging purpose because a part of the region in which the magnetic flux density is most quickly saturated was clipped off from the shield sheet. Thus, charging efficiency can be increased, and the problem of heat generation of the shield sheet can be effectively.

Abstract: An antenna and a mobile terminal having the antenna are discussed. According to an embodiment, the antenna can include a flexible board having a first region and a second region; a high frequency antenna pattern formed in the first region of the flexible board to transceive a wireless signal by detecting a magnetic flux; a low frequency antenna pattern formed in the second region of the flexible board to generate an induced current; and a magnetic sheet stacked on one surface of the flexible board to simultaneously cover both of the high frequency antenna pattern and the low frequency antenna pattern, the magnetic sheet having a high magnetic permeability for both a high frequency and a low frequency.

Abstract: A mobile terminal including a power supply unit including a chargeable battery; a wireless power transmitting unit configured to transform power supplied from the battery into a magnetic field, and to transmit the magnetic field to at least one other terminal placed within a predetermined distance from the mobile terminal; and a controller configured to control an amount of power supplied from the battery to the wireless power transmitting unit.

Abstract: Disclosed is a mobile terminal capable of wirelessly charging a battery using a magnetic induction method. The mobile terminal may include a battery configured to support normal charging mode and fast charging mode, a power pick-up unit configured to pick up power transmitted by a wireless charging device based on magnetic induction, generate a charging voltage based on the pick-up power, and supply the charging voltage to the battery, and a control unit configured to increase the pick-up power by controlling an impedance of the power pick-up unit and increase a charging speed of the battery based on the increased pick-up power in the fast charging mode. The mobile terminal can increase the charging speed of the battery in such a way as to increase pick-up power from power transmitted by the wireless charging device by varying the impedance of the power pick-up unit in fast charging mode.
