1. A mobile terminal comprising:
a first frame;
a second frame slidably movable in a first direction with respect to the first frame to switch to an extended mode, or in a second direction to switch to a default mode, the second direction being opposite to the first direction;
a display unit comprising a fixed part coupled to a front surface of the first frame and a variable part bending around the second frame;
a rolling hinge coupled to a back surface of the variable part, the rolling hinge containing a conductive material;
a ground pin coupled to the rolling hinge; and
a wireless communication module configured to transmit and receive wireless signals,
wherein the second frame comprises:
a ground metal supporting a back surface of the rolling hinge;
a first side metal defining an outer appearance in a third direction perpendicular to the first direction and a fourth direction opposite to the third direction; and
a bottom frame covering a curved portion of the display unit, the bottom frame comprising a second side metal,
wherein at least one of the first side metal and the second side metal is connected to the wireless communication module to transmit or receive the wireless signals,
wherein the ground pin contacts the ground metal in the extended mode to electrically connect the rolling hinge and the ground metal.
