A wireless power reception device can include a first shielding member; a second shielding member; a short-range communication coil on the first shielding member; a wireless charging coil on the second shielding member; and a hole outside the wireless charging coil, in which the hole penetrates through the first shielding member.

Wireless power reception device

A wireless power receiver can include a magnetic substrate and a coil configured to wirelessly receive power. The coil can be formed as a conductive layer on the magnetic substrate. A connecting unit can be disposed in a receiving space of the magnetic substrate and can be connected to the coil unit.

Wireless power receiver and method of manufacturing the same

Disclosed is an antenna assembly including a substrate, and a wireless charge antenna pattern on the substrate. The wireless charge antenna pattern has a sectional surface including a plurality of inner angles in which two inner angles are different from each other. The antenna assembly includes a wireless communication antenna pattern formed on the substrate and provided at an outside of the wireless charge antenna pattern. The wireless communication antenna pattern has a plurality of inner angles at a sectional surface thereof, and a plurality of angle values of the inner angles provided at the sectional surface of the wireless communication antenna pattern correspond to a plurality of angle values of the inner angles provided at the sectional surface of the wireless charge antenna pattern, respectively.

Antenna assembly and method for manufacturing same

A wireless power reception device can include a first shielding member; a mounting member on the first shielding member; a short-range communication coil on the mounting member; a second shielding member inside the short-range communication coil; a wireless charging coil inside the short-range communication coil; and an alignment hole outside the wireless charging coil, in which the alignment hole penetrates through the first shielding member and the mounting member.

A wireless power reception device includes an inner coil, a mounting member having the inner coil mounted thereon and a slit formed in an edge of the inner coil, and a first shielding member and a second shielding member laminated on the first shielding member and provided in correspondence with the inner coil, the mounting member being mounted on the first shielding member and the second shielding member. Accordingly, it is possible to improve efficiency of the wireless power reception device.

A wireless power receiver for wirelessly receiving power from a wireless power transmitter according to the embodiment includes a reception coil part resonance-coupled with the wireless power transmitter to receive the power, and an eddy current prevention part disposed at one side of the reception coil part to prevent an eddy current from being generated from the wireless power receiver caused by a magnetic field generated from the reception coil part.

Wireless power transmitter and wireless power receiver

Disclosed are a shielding apparatus and a wireless power transmission apparatus. The shielding apparatus included in a wireless power transmission apparatus for transmitting power to a wireless power reception apparatus in wireless includes a first shielding unit changing a transmission path of a portion of a magnetic field generated from a transmission coil of the wireless power transmission apparatus, and a second shielding unit shielding the portion of the magnetic field which has passed through the first shielding unit. The second shielding unit is placed on the first shielding unit. A real component value of permeability of the first shielding unit is greater than an imaginary component value of the permeability of the first shielding unit, and an imaginary component value of permeability of the second shielding unit is greater than a real component value of the permeability of the second shielding unit.
