ANTENNA STRUCTURE

Abstract: an antenna structure includes a feeding radiation element, a first grounding radiation element, a second grounding radiation element, a connection radiation element, an extension radiation element, and a dielectric substrate. the feeding radiation element has a feeding point. the first grounding radiation element has a first grounding point. the first grounding radiation element is adjacent to the feeding radiation element. the second grounding radiation element has a second grounding point. the connection radiation element is coupled between the first grounding radiation element and the second grounding radiation element. the extension radiation element is coupled to the connection radiation element. a closed slot is surrounded by the connection radiation element and the extension radiation element. the feeding radiation element, the first grounding radiation element, the second grounding radiation element, the connection radiation element, and the extension radiation element are all disposed on the dielectric substrate.
