Abstract:
1. A broadband antenna applied to multiple frequency bands, comprising: a substrate; a ground plane, disposed on the substrate and having a shorting point, a first grounding point and a second grounding point; a radiating path disposed on the substrate and adjacent to the ground plane, the radiating path having a feeding point disposed on one end thereof, the feeding point corresponding to the first grounding point, and the radiating path having a first connecting point formed thereon; a shorting path disposed on the substrate, two ends of the shorting path respectively electrically connected with the shorting point and the feeding point, and the shorting path having a second connecting point formed thereon; a first connection path disposed on the substrate, two ends of the first connection path respectively electrically connected with the first connecting point and the second, connecting point; a second connection path disposed on the substrate, two ends of the second connection path respectively electrically connected with the first grounding point and the feeding point; and a coupling path disposed on the substrate, one end of the coupling path electrically connected to the second grounding point and another end of the coupling path separated from the shorting path by a predetermined distance.
