Claim:
1. A broadband antenna, comprising: a first feeding portion; a second feeding portion; a grounding portion; a low band radiating unit connected to the first feeding portion, the low band radiating unit establishing a first current path to generate a low band frequency; a high band radiating unit connected to the second feeding portion and spaced from the low band radiating unit, the high band radiating unit establishing a second current path to generate a first high band frequency; and a resonating unit connected to the grounding portion and spaced apart from the high band radiating unit, the resonating unit establishing a third current path to generate a second high band frequency, and resonate with the high band radiating unit to generate a third high band frequency; wherein the low band radiating unit is a meander monopole antenna, and comprises a plurality of U-shaped radiators, a first connecting strip, and a plurality of second connecting strips; the radiators are positioned in a same plane and are connected in sequence by the second connecting strips; the first connecting strip connects between one of the radiators and the first feeding portion; the first connecting strip and the second connecting strips are positioned in a plane that is substantially perpendicular to the plane in which the radiators are positioned; wherein the high band radiating unit comprises a first radiating portion, a second radiating portion, and a third radiating portion, the first radiating portion is a trapezoidal strip, the second radiating portion substantially perpendicularly extends from the first radiating portion, the third radiating portion substantially perpendicularly extends from an end of the second radiating portion opposite to the first radiating portion; the second radiating portion and the third radiating portion are positioned in a plane that is substantially perpendicular to a plane in which the first radiating portion is positioned; wherein the resonating unit comprises a first resonating arm, a second resonating arm, a third resonating arm, and a fourth resonating arm, the first resonating arm is coplanar with the first radiating portion, the second resonating arm extends from the first resonating arm, the third resonating arm extends from the second resonating arm, the fourth resonating arm extends from the third resonating arm, the second, third and fourth resonating arms are coplanar with the second radiating portion.
