Abstract
An antenna structure includes a metal mechanism element, a first radiation element, a second radiation element, a third radiation element, and a dielectric substrate. The metal mechanism element has a slot with a first closed end and a second closed end. The first radiation element has a feeding point. The second radiation element is coupled to the feeding point. The second radiation element and the first radiation element substantially extend away from each other. The third radiation element is coupled to a ground voltage. The third radiation element extends across the slot of the metal mechanism element. The dielectric substrate has a first surface and a second surface opposite to each other. The first radiation element, the second radiation element, and the third radiation element are disposed on the first surface of the dielectric substrate. The second surface of the dielectric substrate is adjacent to the slot.
