Mobile terminal and coil antenna module

Abstract

There is disclosed a mobile terminal including a first case comprising a battery loading portion, a battery loaded in the battery loading portion, a second case coupled to the first case and configured to cover the battery, a coil antenna module arranged between the second case and the battery, and a controller electrically connected to the coil antenna module and configured to transmit and receive a signal or receive an electric power, wherein the coil antenna module includes an insulating sheet, a first coil arranged in a surface of the insulating sheet, a second coil arranged in the first coil, a third coil arranged in the second coil, and a magnetic sheet disposed on the surface of the insulating sheet, and ends of the first, second and third coils are arranged in the surface of the insulating sheet or dividedly arranged in both surfaces of the insulating sheet. The mobile terminal may realize the coil antenna module including a plurality of coils configured to perform diverse manners of wireless communication in a limited area.

What is claimed is: 
     
         1 . A mobile terminal comprising:
 a display;   a battery;   a rear cover disposed to cover the battery;   a controller;   a coil antenna module comprising a plurality of coils including at least a first coil and an integrated coil positioned between the battery and the rear cover,   wherein the coil antenna module is configured to:   provide a near field communication (NFC) function, wherein the NFC function is provided with a frequency band of 13.56 MHz or more using the first coil;   automatically perform a wireless charging function of the battery using the integrated coil when the mobile terminal is placed at a wireless charging device, wherein the wireless charging function is performed with a frequency band according to a Wireless Power Consortium (WPC) standard or a Power Matters Alliance (PMA) standard; and   perform a wireless payment function for transmitting a payment signal using the integrated coil, wherein the wireless payment function is performed with a frequency band of 100 kHz or less,   wherein the controller is configured to control the coil antenna module such that the wireless charging function and the mobile payment function cannot be performed simultaneously.
