Abstract: Provided is a watch-type terminal including: a main body that includes an antenna module which transmits and receives a wireless signal in a predetermined frequency band; a band that extends from the main body and that is formed in such a manner that the main body is removably worn on a wrist; a ground portion that includes first and second metal members that extend to have different lengths; a sensing unit that detects whether or not the main body is worn on the wrist; and a controller that grounds the antenna module to at least one of the first and second metal members, based on whether or not the main body is worn on the wrist.

Abstract: A mobile terminal, comprises: a case including a conductive metal part; a main board mounted inside the case and having a power supply part and a ground surface; a first antenna radiator disposed so as to be spaced from the power supply part to the first antenna radiator; a power supply line for electrically connecting the power supply part to the first antenna radiator and ground line for electrically connecting the ground surface to the metal part and the first antenna radiator, thereby preventing a decrease in the performance of an antenna since the formation of an electromagnetic field between the case of a metallic material and the main board can be minimized even if the metallic material is used for the case.
