| 20090128420 | Dual band antenna - An antenna applied in a communication device is provided. The antenna includes a conductive supporting portion, a radiator and a grounding portion. The radiator operates in a first frequency band. The grounding portion is connected to the radiator through the conductive supporting portion. The grounding portion includes a cavity extended from a top surface of the grounding portion into the interior of the grounding portion. A resonant cavity operating in a second frequency band is formed between the radiator and the cavity. | 05-21-2009 |
| 20100164824 | DIPOLE ANTENNA - A dipole antenna includes a substrate, a first conductive slice and a second conductive slice. The substrate has a first surface, a second surface and a first conductive hole. The second surface is disposed opposite to the first surface, and the first conductive hole passes through the first surface to the second surface. The first conductive slice is disposed on the first surface and has a feeding point. The second conductive slice is disposed on the second surface and has a ground point. The first conductive slice and the second conductive slice are disposed interlacedly and electrically connected to each other via the first conductive hole. The total length of the first conductive slice, the second conductive slice and the first conductive hole has to match the operating frequency of the dipole antenna. | 07-01-2010 |

The area of the second radiating part is larger than that of the first radiating part. The second radiating body is disposed opposite to the first radiating body and has a third radiating part and a fourth radiating part. The area of the third radiating part is larger than that of the first radiating part. The area of the second radiating part is larger than that of the fourth radiating part. The first radiating part or the third radiating part has a feeding point. The second radiating part or the fourth radiating part has a ground point. The first radiating part is electrically connected to the third radiating part. The second radiating part is electrically connected to the fourth radiating part. | 07-01-2010 |
| 20100177002 | DIPOLE ANTENNA - The antenna includes a substrate, a radiation part and a ground part. The radiation part is disposed on the substrate. The outside frame of the radiation part is similar to D-type. The radiation part has at least a hole inside. The ground part is also disposed on the substrate. The ground part has at least a hole inside. Positions of a feeding terminal and a ground terminal of the antenna are not limited to center regions of the sides of the radiation part and the ground part. | 07-15-2010 |
| 20110043410 | Unsymmetrical dual band antenna - An unsymmetrical dual-band antenna including a substrate, a first radiation unit, a second radiation unit and an impedance matching unit is provided. The substrate has a first surface and a second surface opposite to the first surface. The first radiation unit disposed on the first surface of the substrate includes first and second radiation portions connected to each other. The second radiation unit disposed on the first surface of the substrate includes third and fourth radiation portions connected to each other. The third radiation portion is disposed on the first surface of the substrate and adjacent to the first radiation portion. The impedance matching unit disposed on the second surface includes first to fourth patches. The first and the second patch are electrically connected to a feeding point. The third and the fourth patch are electrically connected to a ground point. | 02-24-2011 |
