Abstract
An antenna for WWAN is disclosed, which includes a first radiating metal strip, a second radiating metal strip, a first ground strip, a connecting metal strip and a second ground strip. The first radiating metal strip has a first portion and a second portion. The second radiating metal strip is independent. The first portion is coupled with the second radiating metal strip to induce a first resonance. The second portion cooperates with the second radiating metal strip to induce a second resonance. The connecting metal strip connects the first radiating metal strip to the first ground strip. The second ground strip is independent. The ground strips are used for grounding effect and can be selectively connected to a ground end of a wireless electronic device. Therefore, the antenna can be mounted in any place of the wireless electronic device, and has stable electrical characteristic.
