and an antenna having at least one winding such that an NFC signal for acquiring product information from a product proceeds toward a user's hand, and passing through the body and arranged along the circumference of the band. ## Claims ### Claim 1 A watch-type mobile terminal comprising: a touchscreen; a power supply unit; a main body; a band connected to the main body and configured to be worn on a user's wrist; an antenna having at least one turn such that a Near Field Communication (NFC) signal for acquiring product information from a product proceeds toward a user's hand, and arranged along a circumference of the band through the main body; and a controller configured to: control the power supply unit to change power applied to the antenna in order to reduce a strength of the NFC signal when a plurality of product information is acquired from a plurality of products, wherein the strength of the NFC signal is reduced such that product information of only one of the plurality of products is acquired; determine that an error occurs when product information is acquired from more than one of the plurality of products; control the power supply unit to further reduce the strength of the NFC signal when the error occurs; determine that no error occurs when the product information is acquired from the only one of the plurality of products that is located at the user's hand; and cause the touchscreen to display the acquired product information corresponding to the only one of the plurality of products. ### Claim 2 (depends on 1) The watch-type mobile terminal according to claim 1, wherein the antenna comprises: a first antenna; a second antenna facing the first antenna and disposed at one side of the first antenna; and a third antenna facing the first antenna, disposed at the other side of the first antenna, and adjacent to the user's hand. ### Claim 3 (depends on 2) The watch-type mobile terminal according to claim 2, wherein the first antenna is a feeding antenna for receiving power for generating the NFC signal, wherein the second antenna is a reflecting antenna for reflecting the NFC signal toward the third antenna, and wherein the third antenna is a directional antenna for guiding the NFC signal toward the user's hand. ### Claim 4 (depends on 2) The watch-type mobile terminal according to claim 2, wherein the third antenna includes at least one antenna. ### Claim 5 (depends on 2) The watch-type mobile terminal according to claim 2, wherein the antenna further comprises a capacitor disposed between one end and the other end of each of the first to third antennas. ### Claim 6 (depends on 5) The watch-type mobile terminal according to claim 5, wherein a capacitance value of the capacitor included in the third antenna is less than that of the capacitor included in the first antenna. ### Claim 7 (depends on 5) The watch-type mobile terminal according to claim 5, wherein a capacitance value of the capacitor included in the first antenna is less than that of the capacitor included in the second antenna. ### Claim 8 (depends on 5) The watch-type mobile terminal according to claim 5, wherein the capacitor is disposed in the main body. ### Claim 9 (depends on 2) The watch-type mobile terminal according to claim 2, wherein one end and the other end of the second antenna are connected to each other. ### Claim 10 (depends on 1) The watch-type mobile terminal according to claim 1, wherein the antenna comprises: a first antenna having a plurality of first rotation turns; and a second antenna having a plurality of second rotation turns and disposed on the first antenna. ### Claim 11 (depends on 10) The watch-type mobile terminal according to claim 10, wherein the first antenna and the second antenna have different rotation directions, and wherein the first antenna is arranged along the circumference of the band through the main body. ### Claim 12 (depends on 11) The watch-type mobile terminal according to claim 11, wherein the rotation direction of the second antenna is perpendicular to that of the first antenna. ### Claim 13 (depends on 12) The watch-type mobile terminal according to claim 12, wherein, when the first antenna is wound on an x-y plane in a first rotation direction, the second antenna is wound on an x-z plane in the first rotation direction or in a second rotation direction opposite to the first rotation direction. ### Claim 14 (depends on 12) The watch-type mobile terminal according to claim 12, wherein, when the first antenna is wound on an x-y plane in a first rotation direction, the second antenna is wound on an y-z plane in the first rotation direction or in a second rotation direction opposite to the first rotation direction. ### Claim 15 (depends on 10) The watch-type mobile terminal according to claim 10, wherein the second antenna is disposed in the main body. ### Claim 16 (depends on 10) The watch-type mobile terminal according to claim 10, wherein the first antenna is wound in a circular shape, and wherein the second antenna is wound in a rectangular shape. ### Claim 17 (depends on 10) The watch-type mobile terminal according to claim 10, wherein a size of the second antenna is less than that of the first antenna. ### Claim 18 (depends on 10) The watch-type mobile terminal according to claim 10, wherein the second antenna includes at least one antenna.
