PURPOSE: An internal loop antenna having a multiple band characteristic is provided to realize an internal antenna for a multiple band terminal including a GPS(Global Positioning System) by combining a loop antenna and an inverse F-type antenna. CONSTITUTION: A power feed element is connected with a terminal PCB(Printed Circuit Board) to supply a current to an antenna. A ground element is connected with the terminal PCB to ground the antenna. A first radiating element(34) has one end connected with the power feed element and the other end connected with the ground element, operates in half-wavelength of dynamic frequency, and is formed of a loop structure. A second radiating element(35) has one end connected with the ground element, and the other end is open in a direction of the power feed element, operates a quarter-wavelength of the dynamic frequency, and is formed of an inverse F-structure that the power feed element and the ground element are changed in position. A housing part(37) is formed to install the first and second radiating elements(34,35).
