Abstract

An electronic device includes a first housing, a second housing, and a wireless charging antenna. The second housing is connected to the first housing such that the position thereof relative to the first housing is variable. The wireless charging antenna includes a shielding member and a reception coil alternately wound on a first surface of the shielding member and a second surface opposite to the first surface, and is disposed in at least one of the first housing and the second housing. A battery is electrically connected to the wireless charging antenna.

Claims (43)

1 . An electronic device comprising:

a first housing;

a second housing movably coupled to the first housing;

a wireless charging antenna which comprises a shielding member and a reception coil alternately wound on a first surface of the shielding member and a second surface opposite to the first surface, the wireless charging antenna being disposed in at least one of the first housing and the second housing; and

a battery electrically connected to the wireless charging antenna,

wherein a first portion of the reception coil is disposed on the first surface of the shielding member, and

wherein a second portion of the reception coil is disposed on the second surface of the shielding member.

2 . The electronic device of claim 1 , wherein the reception coil of the wireless charging antenna is wound such that the first surface of the shielding member and the second surface of the shielding member have patterns substantially corresponding to each other.

3 . The electronic device of claim 2 , wherein the wireless charging antenna is disposed in at least one of the first housing and the second housing such that a winding center of the reception coil is adjacent to a center of the electronic device.

4 . The electronic device of claim 1 , wherein the wireless charging antenna comprises:

a first wireless charging antenna comprising a first shielding member and a first reception coil alternately wound on a first surface of the first shielding member and a second surface opposite to the first surface, the first wireless charging antenna being disposed in the first housing; and

a second wireless charging antenna comprising a second shielding member and a second reception coil configured to be alternately wound on a first surface of the second shielding member and a second surface opposite to the first surface, the second wireless charging antenna being disposed in the second housing.

5 . The electronic device of claim 4 , wherein the first wireless charging antenna comprises a first center which is a winding center of the first reception coil,

wherein the second wireless charging antenna comprises a second center which is a winding center of the second reception coil, and

wherein the first wireless charging antenna and the second wireless charging antenna are arranged such that at least one of the first center of the first reception coil and the second center of the second reception coil is adjacent to the center of the electronic device.

6 . The electronic device of claim 4 , further comprising:

a display module of which at least a portion is drawn into or withdrawn from a receiving space of the electronic device in accordance with the second housing with respect to the first housing,

wherein a distance between the first center of the first wireless charging antenna and the second center of the second wireless charging antenna is changed when the second housing slides with respect to the first housing.

7 . The electronic device of claim 6 , wherein the distance between the first center of the first wireless charging antenna and the second center of the second wireless charging antenna is shorter when the display module is withdrawn from the receiving space than when the display module is inserted into the receiving space.

8 . The electronic device of claim 6 , wherein the first wireless charging antenna and the second wireless charging antenna are arranged to form a concentric circle pattern when one surface of the electronic device is viewed in a first direction while the display module is withdrawn from the receiving space.

9 . The electronic device of claim 6 , wherein the second wireless charging antenna is positioned in a first direction with respect to the first wireless charging antenna while the display module is inserted into the receiving space, and

wherein the first wireless charging antenna at least partially overlaps the second wireless charging antenna when one surface of the electronic device is viewed in the first direction.

10 . The electronic device of claim 9 , wherein, in a state where the display module is inserted into the receiving space, a distance between the first center of the first wireless charging antenna and the second center of the electronic device is shorter than a distance between the second center of the second wireless charging antenna and the center of the electronic device.

11 . The electronic device of claim 4 , wherein the first housing and the second housing are foldably connected to each other.

12 . The electronic device of claim 11 , wherein the first wireless charging antenna and the second wireless charging antenna are arranged to form a concentric circle pattern when one surface of the electronic device is viewed in a first direction while the first housing and the second housing are unfolded.

13 . The electronic device of claim 11 , wherein the second wireless charging antenna is positioned in a first direction with respect to the first wireless charging antenna while the first housing and the second housing are folded, and

wherein the first wireless charging antenna at least partially overlaps the second wireless charging antenna when one surface of the electronic device is viewed in the first direction.

14 . The electronic device of claim 1 , wherein an induced current is generated in the reception coil by an externally applied magnetic field, and

wherein when one surface of the electronic device is viewed in a first direction, directions of induced currents flowing in a portion of the reception coil disposed on the first surface of the shielding member and a portion of the reception coil disposed on the second surface of the shielding member are opposite to each other.

15 . The electronic device of claim 1 , wherein the shielding member is configured to shield noise generated by electromagnetic force and/or operating frequency of the wireless charging antenna.

16 . A wireless charging antenna included in an electronic device in which a first housing and a second housing are movably coupled to each other, the wireless charging antenna being disposed in at least one of the first housing and the second housing and comprising:

a shielding member; and

a reception coil alternately wound on a first surface of the shielding member and a second surface opposite to the first surface,

wherein a first portion of the reception coil is disposed on the first surface of the shielding member, and

wherein a second portion of the reception coil is disposed on the second surface of the shielding member.

17 . The wireless charging antenna of claim 16 , wherein the reception coil of the wireless charging antenna is wound such that the first surface of the shielding member and the second surface of the shielding member have patterns substantially corresponding to each other.

18 . The wireless charging antenna of claim 16 , wherein the wireless charging antenna comprises:

a first wireless charging antenna comprising a first shielding member and a first reception coil configured to be alternately wound on a first surface of the first shielding member and a second surface opposite to the first surface, the first wireless charging antenna being disposed in the first housing; and

a second wireless charging antenna comprising a second shielding member and a second reception coil configured to be alternately wound on a first surface of the second shielding member and a second surface opposite to the first surface, the second wireless charging antenna being disposed in the second housing.

19 . The wireless charging antenna of claim 18 , wherein the first wireless charging antenna comprises a first center which is a winding center of the first reception coil,

wherein the second wireless charging antenna comprises a second center which is a winding center of the second reception coil, and

wherein a distance between the first center of the first wireless charging antenna and the second center of the second wireless charging antenna is changed when the second housing slides with respect to the first housing.
