<p>An electronic device comprises a wireless frequency transmission and reception circuit and an antenna structure. The antenna structure comprises an antenna resonance element, a parasitic antenna resonance element, and an antenna ground structure. The antenna structure comprises a metal trace covered with a plastic carrier which is drooped. The plastic carrier includes the metal trace combined with a metal bracket using soldering projected through the hole of the metal bracket. A printed circuit board can be mounted between the metal bracket and the metal housing. The metal housing includes a protrusion-ridge unit held between the prongs on the metal bracket. The cover covers the metal trace on the plastic carrier. The antenna structure is mounted between the hinge structures combined with the upper and the lower housing structure. The antenna structure is operated with the performance when the upper and the lower housing structure are opened or closed.</p> |
