Abstract

An antenna device includes a grounding element and an antenna. The antenna includes a feeding element, first and second radiating elements, and a parasitic element. The first radiating element is coupled to the grounding element. The second radiating element is coupled to the feeding element, is disposed proximate to the first radiating element, and cooperates with the grounding element and the first radiating element to define an area thereamong. The parasitic element is disposed in the area and extends from the grounding element.

Dependent claims

An antenna device, comprising:

a grounding element;
and
a first antenna including
a feeding element that is spaced apart from said grounding element,
a first radiating element that has a first end portion, which is coupled to said grounding element, and a second end portion,
a second radiating element that has a first end portion, which is coupled to said feeding element, and a second end portion, which is disposed proximate to said second end portion of said first radiating element, said second radiating element cooperating with said grounding element and said first radiating element to define a first area thereamong, and
a parasitic element that is disposed in said first area and that extends from said grounding element.
