ABSTRACT:
The present invention relates to an ultra wideband (UWB) internal antenna. The ultra wideband internal antenna includes a first radiation part, a feeding line, a second radiation part, and a ground part. The first radiation part is formed on a top surface of a dielectric substrate and provided with an internal slot. The feeding line supplies a current to the first radiation part. The second radiation part is formed in the internal slot of the first radiation part on the top surface of the dielectric substrate, the second radiation part being conductive. The ground part grounds both the first and second radiation parts. 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.
