An antenna device includes a grounding element, a radiating element, and first and second feeding elements. The radiating element includes a first segment that extends from the grounding element and that has an end distal from the grounding element, and second and third segments that extend from the end of the first segment in opposite directions. Each of the first and second feeding elements includes first and second segments. The first segment of each of the first and second feeding elements is disposed proximate to a respective one of the second and third segments of the radiating element. The second segment of each of the first and second feeding elements is disposed proximate to the grounding element.
