ANTENNA STRUCTURE

Abstract: an antenna structure includes a feeding radiation element, a first radiation element, a second radiation element, an extension radiation element, and a dielectric substrate. the feeding radiation element has a feeding point. the first radiation element is coupled to a ground voltage. the first radiation element is adjacent to the feeding radiation element. the second radiation element is coupled to the ground voltage. the second radiation element is adjacent to the feeding radiation element. the extension radiation element is coupled to the first radiation element. the feeding radiation element and the second radiation element are at least partially surrounded by the first radiation element. the feeding radiation element, the first radiation element, the second radiation element, and the extension radiation element are all disposed on the dielectric substrate.
