Electronic device for reducing interference between a charging coil and an antenna
An electronic device is provided. The electronic device includes a main body including a battery pack and a battery cover; a non-contact near field communication antenna included in the battery pack; and a wireless charging coil portion included in the battery cover and disposed around an outer periphery of the antenna, such that the wireless coil portion does not overlap with the non-contact near field communication antenna.
1. An electronic device comprising:
a main body including a battery pack and a battery cover;
a non-contact near field communication antenna included in the battery pack; and
a wireless charging coil portion included in the battery cover and disposed around an outer periphery of the non-contact near field communication antenna, such that the wireless coil portion does not overlap with the non-contact near field communication antenna.
2. The electronic device of claim 1 , wherein the wireless charging coil portion includes a shielding portion disposed along the wireless charging coil portion and having a shape corresponding to a shape of the wireless charging coil portion.
3. The electronic device of claim 2 , wherein the shielding portion is made from ferrite or a polymer.
4. The electronic device of claim 1 , wherein the non-contact near field communication antenna uses the frequency bands ranging from 12 to 14 MHz, and the wireless charging coil portion uses the frequency bands ranging from 100 KHz to 14 MHz.
5. The electronic device of claim 2 , wherein the battery cover is formed with a seating groove for seating the wireless charging coil portion and the shielding portion.
6. The electronic device of claim 1 , wherein a predetermined distance is defined between the non-contact near field communication antenna and the wireless charging coil portion.
7. An electronic device comprising:
a main body including a battery pack and a battery cover;
a non-contact near field communication antenna included in the battery pack; and
a wireless charging coil portion included in the battery cover and disposed within an inner side of the non-contact near field communication antenna, such that the wireless coil portion does not overlap with the non-contact near field communication antenna.
8. The electronic device of claim 7 , wherein the wireless charging coil portion includes a shielding portion disposed along the wireless charging coil portion and having a shape corresponding to a shape of the wireless charging coil portion.
9. The electronic device of claim 8 , wherein the shielding portion is made from ferrite or a polymer.
10. The electronic device of claim 7 , wherein the non-contact near field communication antenna uses the frequency bands ranging from 12 to 14 MHz, and wherein the wireless charging coil portion uses the frequency bands ranging from 100 KHz to 14 MHz.
11. The electronic device of claim 8 , wherein the battery cover is formed with a seating groove for seating the wireless charging coil portion and the shielding portion.
12. The electronic device of claim 7 , wherein the inner side of the non-contact near field communication antenna is formed with a hole that receives the wireless charging coil portion.
13. An electronic device comprising:
a main body including a battery pack and a battery cover;
a non-contact near field communication antenna included in the battery pack; and
a wireless charging coil portion included in the battery cover that prevents the wireless coil portion from overlapping with the non-contact near field communication antenna.
14. The electronic device of claim 13 , wherein the wireless charging coil portion is disposed around an outer periphery of the non-contact near field communication antenna or within an inner side of the non-contact near field communication antenna.
15. An electronic device comprising:
a main body;
an antenna included in the main body; and
a wireless charging coil portion included in a cover of the main body that prevents the wireless coil portion from overlapping with the antenna,
wherein the wireless charging coil portion is disposed around an outer periphery of the antenna or within an inner side of the antenna.
16. The electronic device of claim 15 , wherein the wireless charging coil portion includes a shielding portion disposed along the wireless charging coil portion and having a shape corresponding to a shape of the wireless charging coil portion.
