Abstract
A communication device has an antenna structure including a substrate, a ground element, an open slot and a radiating metal portion. The ground element is disposed on a first surface of the substrate. The open slot is formed on the ground element and substantially 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 shorter than 0.05 wavelength of a center frequency of the first resonant mode. The radiating metal portion is 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.
