Abstract

The invention relates to an integrated antenna for a portable computer. The portable computer has a main frame. The integrated antenna comprises a substrate, a first radiating metal strip, a second radiating metal strip, a ground plane, at least one first connecting metal strip and second connecting metal strip. The substrate has a connecting portion for connecting to the main frame. The first radiating metal strip is used to induce a first resonance, and the second radiating metal strip is used to induce a second resonance. The first connecting metal strip connects to the first radiating metal strip and the second radiating metal strip. The second connecting metal strip connects to the second radiating metal strip and the ground plane. The integrated antenna of the invention is mounted to the main frame of the portable computer. The length of a coaxial cable can be reduced. Therefore, the transmission loss and cost can be reduced. Furthermore, the integrated antenna can be easily mounted on the main frame of portable computer.
