ABSTRACT:
An ultra-wide bandwidth antenna includes a dielectric substrate, first and second conductive elements, and a third conductive element. The dielectric substrate has opposite first and second surfaces. The first conductive element is formed on the second surface of the dielectric substrate and has a feeding point. The second conductive element is formed on the second surface of the dielectric substrate, is spaced apart from the first conductive element, and has a grounding point. The third conductive element is formed on the first surface of the dielectric substrate, partially overlaps the first conductive element, and is coupled electrically to the second conductive element.
