1. A planar antenna operable within the ultra wide bandwidth, comprising:

  • a dielectric substrate having opposite first and second surfaces;

    an elliptical radiating element formed on said first surface of said dielectric substrate, and having major and minor axes, the ratio of the major axis to the minor axis being between 1.25 and 1.7;

    a feeding element formed on said first surface of said dielectric substrate, and coupled to said radiating element; and

    a grounding element formed on said second surface of said dielectric substrate, and coupled to said feeding element.
