Antenna structure

Abstract

An antenna structure includes a metal mechanism element, a dielectric substrate, a feeding radiation element, and a coupling radiation element. The metal mechanism element has a slot. The slot has a first closed end and a second closed end. The dielectric substrate has a first surface and a second surface which are opposite to each other. The feeding radiation element is coupled to a signal source, and is disposed on the second surface of the dielectric substrate. The feeding radiation element has a first vertical projection on the metal mechanism element. The coupling radiation element is coupled to a ground voltage, and is disposed on the first surface of the dielectric substrate. The coupling radiation element has a second vertical projection on the metal mechanism element. The second vertical projection of the coupling radiation element at least partially overlaps the first vertical projection of the feeding radiation element.
