Abstract: A mobile terminal including a terminal body having a display unit disposed on one surface thereof; a frame supporting the display unit; a metal member spaced apart from the frame and exposed to an outside of the mobile terminal; a plurality of connecting members connecting the metal member to the frame and grounding the metal member; and an antenna unit disposed adjacent to the frame and including a radiator radiating wireless signals in a first frequency band. Further, the metal member is divided into specific areas by the connecting members, and one area located adjacent to the radiator, generates a parasitic resonance at a second frequency band different from the first frequency band, and a frequency band of the antenna unit is shifted to a third frequency band including the first frequency band by the metal member and the radiator when a dielectric is placed adjacent to the metal member.

Abstract: There is disclosed a mobile terminal comprising a body; a ground of a printed circuit board loaded in the body; a data port located in the body to have an external input terminal inserted therein and connected with the ground; a metallic member defining an exterior of the body and comprising a slit; a feeding portion connected with a first point of the metallic member and configured to supply power; a first ground line connected with the ground at a second point located between the first point of the metallic member and the slit; and a second ground line connected with the data port connected with the ground when the external input terminal is inserted in the data port, so that the mobile terminal has to include no additional switch to reduce the number of the components and the antenna of the mobile terminal may be selectively and structurally connected without the algorithm configured to manipulate the switch by sensing that the external input terminal is inserted in the data port to operate the switch to minimize the expense increase cost to improve the antenna performance.
