Abstract
An antenna structure includes a ground element, a feeding radiation element, a first radiation element, a second radiation element, a first coupling branch, and a dielectric substrate. The feeding radiation element has a feeding point. The first radiation element is coupled to the feeding radiation element. The second radiation element is coupled to the feeding radiation element. The second radiation element and the first radiation element substantially extend in opposite directions. The first coupling branch is coupled to a first grounding point on the ground element. The first coupling branch extends across the first radiation element. The first coupling branch includes a first coil portion and a first connection portion.
