The broadband antenna has a radiating element, a grounding element, a short-circuiting element and a feeding plane. The radiating element has a first radiation area and a second radiation area, the first radiation area and the second radiation area perpendicularly connected to each other substantially. The feeding plane perpendicularly connected to the second radiation area substantially, the feeding plane comprising a feeding point, a first end and a second end; wherein a distance between the feeding point and the first end is less than a distance between the feeding point and the second end. The short-circuiting element is used for connecting the first radiation area with the grounding element or connecting the feeding plane with the grounding element. ## Claims ### Claim 1 A broadband antenna comprising: a radiating element having a first radiation area and a second radiation area, the first radiation area and the second radiation area perpendicularly connected to each other substantially;
