Abstract
An antenna structure includes a metal mechanism element, a ground element, a feeding radiation element, and a dielectric substrate. The metal mechanism element has a slot. The slot has a first closed end and a second closed end. The ground element is coupled to the metal mechanism element. The feeding radiation element has a feeding point. The feeding radiation element is coupled to the ground element. The dielectric substrate has a first surface and a second surface which are opposite to each other. The feeding radiation element is disposed on the first surface of the dielectric substrate. The second surface of the dielectric substrate is adjacent to the metal mechanism element. The slot of the metal mechanism element is excited to generate a first frequency band and a second frequency band. The feeding radiation element is excited to generate a third frequency band.
