| 1. A portable terminal with a variable ground unit, comprising:
a main body receiving a main board including a ground layer having a predetermined area;
at least one antenna radiator placed at the main board;
a sub-body movably coupled to the main body by an electrically conductive hinge module and including at least one conductor
electrically connected to the ground layer by the electrically conductive hinge module;
at least one switching unit interposed between the at least one conductor and the ground layer, the at least one switching
unit selectively connecting the at least one conductor to the ground layer by an electrical connection unit; and
a controller controlling the at least one switching unit so that the at least one conductor and the ground layer of the main
board are selectively electrically connected depending on a state of the terminal.
