摘要： A mobile device includes a ground element, a first radiation element, a second radiation element, and a dielectric substrate. The first radiation element has a feeding point. The first radiation element includes a meandering portion. The second radiation element is coupled to the feeding point, and is at least partially surrounded by the first radiation element. A coupling gap is formed between the first radiation element and the second radiation element. The ground element, the first radiation element, and the second radiation element are all disposed on the dielectric substrate. A planar antenna structure is formed by the first radiation element and the second radiation element. The planar antenna structure covers a TETRA (Terrestrial Trunked Radio) frequency band and a GPS (Global Positioning System) frequency band.
