PURPOSE: An ultra wideband monopole antenna including a parasitic patch of an inverted T shape is provided to enhance productivity efficiency by performing a simple antenna design. CONSTITUTION: An ultra wideband monopole antenna including a parasitic patch of an inverted T shape includes a dielectric substrate, a main radiator, a feeding part, a parasitic radiator, and a ground part. The dielectric substrate(110) has a fixed dielectric constant. The main radiator(150) is formed in one surface of the dielectric substrate, and includes at least one or more notches. The feeding part(140) is extended from a bottom part of the main radiator to a bottom part of one surface. The parasitic radiator(160) is formed in the other surface of the dielectric substrate, and has an inverted T shape. The ground part(170) is separated from the parasitic radiator, and is positioned in a bottom part of the other surface.
