A mobile terminal is provided, which includes a wireless charging module, a battery pack, and a circuit board substrate. The wireless charging module includes a charging coil formed of a wound conducting wire and a communication coil placed adjacent to the charging coil. The wireless charging module has a substantially planar shape. The battery pack has a substantially planar shape and is configured to store power from the wireless charging module. The circuit board substrate is configured to control operation of the mobile terminal. The wireless charging module overlaps with each of the circuit board substrate and the battery pack.

Electronic device including non-contact charging module and battery

A power receiver apparatus is movable under water. The power receiver apparatus includes: a power receiver device configured to receive power wirelessly transmitted from a power transmitter apparatus; a power supply device including a storage battery and configured to charge the storage battery based on received power received by the power receiver device; a first sensor configured to detect a rectified voltage value rectified based on the received power; a second sensor configured to detect a charging current value to the storage battery charged by the power supply device; a processor configured to determine a power transmission voltage value corresponding to the power wirelessly transmitted from the power transmitter apparatus based on the rectified voltage value and the charging current value; and a communication device configured to transmit the power transmission voltage value determined by the processor to the power transmitter apparatus.

Power receiver apparatus, power transmission voltage control method, and underwater power supply system

A mobile terminal is provided with a housing, a circuit board included in the housing and having a thickness direction normal to a plane of the circuit board, a battery pack included in the housing, and a non-contact charging module included in the housing. The non-contact charging module includes a charging coil formed of a wound conducting wire; a communication coil arranged adjacent to the charging coil; and a magnetic sheet on which the charging coil and the communication coil are arranged. The magnetic sheet has four edges that collectively define a rectangular profile of the magnetic sheet, and at most three pairs of adjacent edges respectively meet to form at most three corners. At least a portion of the non-contact charging module overlaps with the circuit board as viewed in the thickness direction of the circuit board.

Mobile terminal and chargeable communication module

Provided is an antenna that can facilitate favorable communications even if no metal body is located near the antenna and even if the antenna is located within a metal body. An antenna is characterized in that the antenna comprises: a core () having a plane; a coil winding part (area B) of the plane about which a coil is wound; and no-coil winding parts (areas A, C) of the plane about which no coil is wound, wherein the coil winding part is sandwiched between the no-coil winding parts in the axial direction of the coil on the plane, and the width of the plane in the axial direction of the coil is equal to or greater than the width of the plane in the winding direction of the coil.

Antenna, antenna device and communication device

A small antenna device having good communications performance and a wide communications area even when a metal plate is present in the antenna communications direction, even when the antenna is arranged, for example, inside a box-shaped metal case, and even when a through hole is used that has a smaller area than the antenna. This device comprises: the antenna; a rear surface cover overlapping with the antenna and being a conductor that faces the winding of the antenna; two first insulating areas provided in the rear surface cover and extending in a direction that intersects the winding axis of the antenna; and a second insulating area that connects between the first insulating areas. At least part of the area sandwiched by the first insulating areas faces the antenna.

Antenna device and communications device

A mobile terminal is provided with a housing having a rectangular shape in a plan view of the housing defined by two short sides along a lateral direction and two long sides along a longitudinal direction. A camera, a battery, and a circuit board are included in the housing. A wireless charging coil is arranged in the housing and includes a winding portion and two leg portions. A sheet is arranged in the housing. The sheet has a rectangular shape including four edges and four corner portions, wherein each pair of adjacent edges forms a virtual corner, each corner portion is receded inwardly from its corresponding virtual corner by a receding distance, and one of four receding distances is greater than other three of the four receding distances.
