Abstract
An antenna structure includes a ground plane, a first radiation element, a second radiation element, a third radiation element, and a dielectric substrate. The ground plane provides a ground voltage. The first radiation element includes a connection branch, a first branch, and a second branch. The connection branch has a feeding point. The first branch and the second branch substantially extend in opposite directions. The second radiation element is coupled to the feeding point. The second radiation element substantially surrounds a non-metal region, and is further coupled to the ground voltage. The third radiation element is coupled to the ground voltage. The third radiation element is adjacent to the first radiation element. The first radiation element, the second radiation element, and the third radiation element are all disposed on the dielectric substrate.
