A planar antenna, which is operable within the ultra wide bandwidth, includes a dielectric substrate, a radiating element, a feeding element, and a grounding element. The dielectric substrate has opposite first and second surfaces. The radiating element is formed on the first surface of the dielectric substrate, and includes a tapered part. The tapered part has a converged end portion, and a pair of jagged sides that diverge from the converged end portion. The feeding element is formed on the first surface of the dielectric substrate, and extends from the converged end portion of the tapered part of the radiating element. The grounding element is formed on the second surface of the dielectric substrate.
