ABSTRACT:
Antenna for use in a mobile communication terminal includes a power feed unit for feeding power to the antenna, a ground unit for grounding the antenna, and a radiation unit formed in a band shape with a designated width. The radiation unit has one end connected to the power feed unit and the other end connected to the ground unit, is arranged along an edge of an upper surface of a dielectric support unit for supporting the antenna so as to form a loop-shaped current path, and radiates at a designated low frequency band when a current is introduced to the power feed unit.
