Patent ID: 7932865

Claim:
A coplanar coupled-fed multiband antenna for mobile communication, comprising: a dielectric substrate; a ground plane located on a surface of the dielectric substrate and having a shorting point located at one edge of the ground plane, and the edge located in the interior of the dielectric substrate; a radiating portion located on a surface of the dielectric substrate and near one edge of the ground plane without overlapping with the ground plane, wherein two ends of the radiating portion are both open ends; a shorting metal portion located on a surface of the dielectric substrate, and located on the surface of the dielectric substrate where the radiating portion is located on, and one end of the shorting metal portion electrically connected to the radiating portion, and the other end of the shorting metal portion connected to the shorting point of the ground plane; and a feeding portion located on the surface of the dielectric substrate where the radiating portion located on, comprising: a first feeding metal portion having a feeding point being the feeding point of the coplanar coupled-fed multiband antenna, and the feeding point connected to a signal source; and a second feeding metal portion separated from the first feeding metal portion by a gap, and one end of the second feeding metal portion connected to the radiating portion.
