| 摘要 |
Various embodiments of an antenna structure for mobile devices are described. In one or more embodiments a multi-band antenna includes first, second and third resonating elements. The first and second resonating elements may each have an L-shape, and may be fed by a single feed leg. The third resonating element may be coupled to ground. In some embodiments, the first resonating element may be longer than the second resonating element, and the third resonating element may be positioned adjacent to the first resonating element. In other embodiments, a tuning element is coupled to the signal feed and is positioned adjacent to the second resonating element. The tuning element may have a geometry that is similar to a geometry of the second resonating element. The combination of these structures creates a plurality of distinct resonance modes which creases a wide effective bandwidth for the disclosed antenna. Other embodiments are described and claimed.
