First Claim
1. A mobile terminal comprising:
- a display;
a battery;
a rear cover disposed to cover the battery;
a coil antenna module positioned between the battery and the rear cover,wherein the coil antenna module comprises;
a base sheet;
a first coil, a second coil, and a third coil, each positioned on the base sheet; and
a magnetic sheet disposed over the first coil, the second coil and the third coil; and
a controller electrically coupled to the coil antenna module and configured to;
provide a near field communication (NFC) function using the first coil with a frequency band of 13.56 MHz;
provide a payment function using the second coil with a frequency band of 100 kHz or less; and
provide a wireless battery charging function using the third coil with a frequency band of 110 kHz to 280 kHz when the mobile terminal is placed at a wireless charging device,wherein the coil antenna module is further configured to;
cause the second coil to not connect to the payment function while the battery is charged via the wireless battery charging function; and
connect the first coil to the NFC function while the second coil is connected to the payment function or the third coil is connected to the wireless battery charging function.
