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.
