Abstract
A mobile communication device includes a ground plane and an antenna. The antenna is disposed on a dielectric substrate and includes a radiating metal portion, a coupling metal portion, and an inductive shorting metal portion. The radiating metal portion provides a resonant path for the antenna to generate first and second operating bands. The coupling metal portion is coupled to the radiating metal portion to form a first coupling portion and is connected to a source through a connecting metal strip. One end of the inductive shorting metal portion is electrically connected to the radiating metal portion, and the other end is electrically connected to the ground plane. The inductive shorting metal portion includes a first fractional section coupled to the radiating metal portion to form a second coupling portion, and a second fractional section coupled to the coupling metal portion to form a third coupling portion.
