Abstract
An antenna structure includes a ground plane, a first radiation element, a second radiation element, a third radiation element, a fourth radiation element, and a dielectric substrate. The first radiation element has a feeding point. The second radiation element is coupled to the feeding point. The non-metal region is substantially surrounded by the first radiation element and the second radiation element. The third radiation element is coupled to a first shorting point on the ground plane. The third radiation element is adjacent to the first radiation element and the second radiation element. The fourth radiation element is coupled to a second shorting point on the ground plane. The fourth radiation element is adjacent to the second radiation element. The ground plane, the first radiation element, the second radiation element, the third radiation element, and the fourth radiation element are all disposed on the dielectric substrate.
