Abstract
An antenna structure includes an antenna holder, a feed unit, a grounding unit, a first radiating unit, a second radiating unit, a third radiating unit, a parasitic unit, and a coupling unit. The feed unit and the grounding unit are positioned on the antenna holder and are spaced apart from each other. The first radiating unit and the third radiating unit are both electrically connected to the feed unit. The parasitic unit is electrically connected to the grounding unit. The first radiating unit couples with the second radiating unit and the parasitic unit. The second radiating unit further couples with the coupling unit and is grounded through the coupling unit.
