Abstract
The present invention is related to a mobile communication device. The device has a ground plane and an antenna. The antenna is disposed on a dielectric substrate and comprises a radiating metal portion, a coupling metal portion, and a shorting metal portion. One edge of the radiating metal portion faces the ground plane and has a distance between the edge and the ground plane. The coupling metal portion is electrically connected to a source via a connecting metal strip. One end of the shorting metal portion is electrically connected to the radiating metal portion, and the other end of the shorting metal portion is electrically connected to the ground plane.
Claims9
A mobile communication device, having a ground plane and an antenna, wherein the antenna is disposed on a dielectric substrate, the antenna comprising:
- a radiating metal portion, having a width and a length, wherein the width is at least one-eighth of the length, an edge of the radiating metal portion faces the ground plane and has a distance between the edge and the ground plane, the edge has a shorting point, the radiating metal portion passes through a central line defined according to the center of the length, and the distance between the shorting point and the central line of the radiating metal portion is less than 15 mm;
- a coupling metal portion, coupling electromagnetic energy to the radiating metal portion via a coupling gap, wherein the coupling metal portion is electrically connected to a source via a connecting metal strip, and the distance between the connecting metal strip and the central line of the radiating metal portion is less than 15 mm;
