1. An embedded ultra-wide band antenna comprising:
- a grounding element;
a radiating element comprising a horizontal portion and a vertical portion, and the horizontal portion and the vertical portion together forms the radiating element substantially in a T shape, wherein the horizontal portion further comprises at least one closed opening for cutting off an undesired band group, the horizontal portion surrounds the closed opening, and the vertical portion further comprises a feed point for feeding current to resonate frequency; and
a plurality of sleeve elements respectively extending from the grounding element, wherein the plurality of sleeve elements comprise two substantially identical first sleeve elements respectively symmetrically located on both sides of the vertical portion and two substantially identical second sleeve elements respectively symmetrically located on the outer side of the first sleeve elements, the second sleeve elements being substantially shorter than the first sleeve elements, and the plurality of sleeve elements and the vertical portion being substantially parallel to each other and arranged in order of length to form a staircase shape.
