Meanwhile, the mobile terminal 100 can transmit and receive data with external devices through short-range wireless communication. However, while the optimized antenna tuning values are different for each of the external devices, the antenna unit of the mobile terminal 100 can support only one antenna tuning value. As a result, there has been a problem in that it is impossible to perform near-field wireless communication optimized for external devices.

Hereinafter, a mobile terminal 100 capable of supporting an optimal antenna tuning value for each of external devices and a control method thereof will be described with reference to the accompanying drawings.

The antenna unit 182 is configured to perform short-range wireless communication with an external device, the NFC chip 183 is connected to the antenna unit 184, and can acquire information from an external device.

In addition, the short-range wireless communication can be divided into a passive communication mode and an active communication mode. In the passive communication mode, an initiator forms an RF field and a target responds by applying a load modulation scheme to the command of the transmitter. On the other hand, in the active communication mode, both the transmitter and the target communicate by forming an RF field.

The external device may be any external device capable of short-range wireless communication, a sticker, a tag, a card, and the like. Specifically, a communication tag is attached to the external device. The mobile terminal 100 receives tag information from a communication tag mounted on an external device. For this, the local area communication unit 114 (see FIG. 1) of the mobile terminal 100 may be configured to perform short-range wireless communication with an external device.

The communication tag may be mounted outside or inside the external device. The communication tag is a medium for storing tag information corresponding thereto. Such tag information may include location information, time information, user information, and the like. The communication tag can provide the tag information to the mobile terminal 100 through the short-range wireless communication. At this time, the communication tag may be referred to as an NFC tag.

Next, step S120 is performed in which a control command related to short-range wireless communication is detected.

Specifically, the user input unit 130 generates input data for controlling the operation of the mobile terminal 100 by the user. The user input unit 130 may include a key pad, a dome switch, a jog wheel, a jog switch, and the like. Also, the user input unit 130 may include a touch pad capable of touch input. The touch pad may be mounted on the front surface of the display unit 151.

Here, the control command related to short-range wireless communication may include a control command for tuning the antenna unit 182 to one of preset tuning values. The user input unit 130 may sense such a control command.

Thereafter, step S130 is performed in which one of the plurality of tuning values is selected based on the control command so that the antenna unit 182 is tuned to the selected tuning value.

To this end, as one embodiment, an electronic element portion 184 may be disposed between the antenna portion 182 and the NFC chip 183. The control unit 180 can control the electronic element unit such that the antenna unit 182 is tuned to the selected tuning value. Specifically, the electronic element portion may include a capacitor element, an inductor element, resistive elements, and switches disposed between the respective elements. The controller 180 may control the switching of the switches included in the electronic device unit such that the antenna unit 182 is tuned to the selected tuning value.
