Mobile Communication Device and Antenna Thereof

摘要

The present invention is related to a mobile communication device comprising a ground plane and an antenna. The antenna is disposed on one surface of a dielectric substrate. The antenna comprises a first radiating metal portion and a second radiating metal portion. The first radiating metal portion has at least one bending. One end of the first radiating metal portion is a feeding point of the antenna and the other end is left open. One end of the second radiating metal portion is short-circuited to the ground plane, and the other end is left open. A length of the second radiating metal portion is 0.75 to 1.25 times that of the first radiating metal portion. At least a portion of the second radiating metal portion is extended along the first radiating metal portion with a gap of less than a specified distance therebetween.
