Abstract

An antenna structure includes the following. A first radiation element has a feeding point. A second radiation element is coupled to the feeding point. A third radiation element is coupled through a capacitive element to the second radiation element. A fourth radiation element is coupled through a tunable circuit to a ground element. The fourth radiation element is adjacent to the first radiation element. A fifth radiation element is coupled to the fourth radiation element. A nonconductive support element has a first surface and a second surface which are opposite to each other. The first radiation element, the second radiation element, the capacitive element, the third radiation element, and the fourth radiation element are disposed on the first surface. The fifth radiation element is disposed on the second surface.
