Abstract
An antenna structure utilizing as radiating elements only the metal frame of an electronic device includes a metal frame, a feeding portion, and a ground point. The metal frame defines a first gap and a second gap. The metal frame forms a radiating portion, a first coupling portion, and a second coupling portion through the first gap and the second gap. When the feed supplies current, the current flows through the radiating portion and, being coupled to the first coupling portion and second coupling portion through the first and second gaps, first, second, and third operating modes at different frequencies can be invoked to generate wireless signals in first, second, and third LTE-A frequency bands.
