Abstract: An antenna structure disposed in a case includes a blocking part, a cooling module, an antenna module, and a ground component. The cooling module is disposed on a side of the blocking part. The antenna module is disposed on the side of the blocking part and has an interval space between the antenna module and the cooling module along a first direction. The ground component is disposed in the interval space, and is electrically connected to the antenna module and the cooling module. The ground component, the antenna module and the cooling module jointly define a slot in the interval space. The antenna module has a resonant frequency, and the antenna module couples and excites the slot to generate another resonant frequency. Thus, the antenna structure of the present disclosure can provide multiple frequency bands and great radiation characteristics in an environment with multiple metals.

Abstract: An antenna structure includes a ground element, a feeding radiation element, a shorting radiation element, a connection radiation element, a first radiation element, and a second radiation element. The feeding radiation element has a feeding point. The feeding radiation element is coupled through the shorting radiation element to the ground element. The connection radiation element is coupled between the first radiation element and the shorting radiation element. The second radiation element is coupled to the feeding radiation element. A coupling slot region is formed and substantially surrounded by the feeding radiation element, the shorting radiation element, the connection radiation element, the first radiation element, and the second radiation element.

Abstract: A convertible mobile device includes an upper cover, a base, a hinge element, a supporting element, an antenna structure, and a cover element. The hinge element is connected between the upper cover and the base, so that the convertible mobile device can flip over and operate in a notebook mode or a tablet mode. The antenna structure is disposed on the supporting element. The antenna structure includes a first radiation element and a second radiation element. One of the first radiation element and the second radiation element has a positive feeding point, and the other of the first radiation element and the second radiation element has a negative feeding point. A coupling gap is formed between the first radiation element and the second radiation element. The cover element covers the supporting element, the antenna structure, and at least a portion of the hinge element.
