1. An ultra wideband internal antenna, comprising:

  • a first radiation part formed on a top surface of a dielectric substrate and provided with an internal slot;

    a feeding line for supplying a current to the first radiation part;

    a second radiation part formed in the internal slot of the first radiation part on the top surface of the dielectric substrate, the second radiation part being conductive; and

    a ground part for grounding both the first and second radiation parts,wherein the second radiation part determines an ultra wideband by mutual electromagnetic coupling with the first radiation part using a current element induced due to the current supplied to the first radiation part.
