Abstract:
1. A slim mobile communication device, comprising an antenna structure, the antenna structure comprising: a dielectric substrate, comprising a no-ground portion and a ground portion, wherein the no-ground portion comprises a first edge used as a feeding edge and a second edge used as a non-feeding edge; a ground element, disposed on the ground portion of the dielectric substrate; an antenna element, that is a planar structure providing a first operating band and a second operating band, and is disposed on the no-ground portion of the dielectric substrate; the first edge and the second edge of the no-ground portion are surrounded by the ground element; wherein a distance between a non-feeding side edge of the antenna element and the second edge of the no-ground portion is smaller than 3 mm, a length of the non-feeding side edge of the antenna element is at least 5 mm, and the non-feeding side edge of the antenna element is short-circuited to the ground element; and a feeding line, coupled to the feeding side edge of the antenna element.
