Abstract
A broadband antenna includes a substrate, a ground plane, a radiating path, a shorting path, a first connection path, a second connection path and a coupling path. The ground plane has a shorting point, a first grounding point and a second grounding point. The radiating path has a feeding point and a first connecting point. Two ends of the shorting path are respectively electrically connected with the shorting point and the feeding point, and the shorting path has a second connecting point. Two ends of the first connection path are respectively connected with the first connecting point and the second connecting point. Two ends of the second connection path are respectively connected with the first grounding point and the feeding point. One end of the coupling path is connected to the second grounding point and another end of the coupling path is separated from the shorting path.
