ABSTRACT:
A loop antenna for a mobile terminal capable of reducing SAR. The loop antenna has three lines. The first line generates and transmits predetermined electric waves upon receiving current from an oscillator for oscillating power and has a connection point to connect an external line thereto. The second line includes a first end connected to a printed circuit board to ground current supplied to the first line and a second end having an opened structure. The third line has a first end connected to one side of the first line through the connection point and a second end connected to one side of the second line coupled to the printed circuit board in order to receive current from the first line through the connection point and transmit current into the second line.
