Claim Text:
1. A communication device, comprising an antenna structure, the antenna structure comprising: a substrate; a ground element, disposed on a first surface of the substrate; an open slot, formed on the ground element and parallel with an edge of the ground element, wherein the open slot at least generates a first resonant mode, and a distance between the open slot and the edge of the ground element is between 0 and 0.05 free-space wavelength of a resonant frequency of the first resonant mode; a radiating metal portion, disposed on a second surface of the substrate, wherein the open slot at least partially covers the radiating metal portion, the radiating metal portion at least generates a second resonant mode, and a feed point of the radiating metal portion is electrically coupled to a signal source on the substrate; and a metal conductor, electrically coupled to the edge of the ground element and perpendicular to the ground element, wherein the metal conductor has a width which is not larger than a thickness of the communication device; the metal conductor is part of a housing of the communication device, and the metal conductor is a planar conductor, and the metal conductor extends along two opposite sides of the ground element.
