Abstract:
1. A watch type mobile terminal comprising: a case whose both ends are connected by a band, the case comprising: a first conductive case forming a surrounding configuration of a window; a second dielectric case assembled to a lower portion of the first conductive case and having an accommodation space part for accommodating a plurality of components therein, wherein the second dielectric case is sized such that at least an entire perimeter of an upper portion of the second dielectric case is enclosed by the first conductive case; and a third conductive case assembled to a lower portion of the second dielectric case, the third conductive case forming a main ground; the first, second, and third cases constitute an external appearance of the watch type mobile terminal; an antenna disposed on an inner surface of a sloped side of the second dielectric case; and a first ground extending part disposed on a side of the second dielectric case opposite the sloped side, wherein: the antenna is positioned to be spaced from the first conductive case by a predetermined gap such that the antenna is electrically coupled with the first conductive case; the antenna comprises: a first conductor configured to be connected to a signal feeding portion; and a second conductor positioned to be separated from the first conductor such that the second conductor is electrically coupled with the first conductor and configured to be connected to a ground feeding unit to be connected to the main ground; the first conductive case, which is made of a conductive material, is electrically coupled with the antenna; and the first ground extending part comprises a conductive layer disposed on an inner side of the second dielectric case and positioned to be adjacent to the first case at a certain interval such that an electrical coupling is generated between the first conductive case and the conductive layer, thereby electrically coupling the main ground of the third case to the first conductive case and improving radio performance.
