Abstract
An antenna structure includes a metal mechanism element, a ground element, a feeding radiation element, a coupling element, a dielectric substrate, and a switchable circuit. The metal mechanism element has a slot. The feeding radiation element extends across the slot. A coupling gap is formed between the feeding radiation element and the coupling element. The feeding radiation element and the coupling element are disposed on the dielectric substrate. The switchable circuit includes a first metal element, a second metal element, a reactance element, a capacitor, and a diode. The first metal element is coupled to the coupling element. The reactance element is embedded in the first metal element. The second metal element is coupled through the capacitor to the ground element. The diode is coupled between the first metal element and the second metal element. The diode is turned on or off according to the control voltage difference.
