| 摘要 |
An internal antenna of small volume comprising: a conductive ground plane; a first conductive surface placed in an antenna plane substantially parallel to the ground plane and partially surrounding a portion of the antenna plane, and presenting first and second ends; a second conductive surface forming a main radiating assembly disposed essentially in said portion of the antenna plane, said two conductive surfaces not being connected together by any conductive electrical connection; an antenna conductor connected to said second conductive surface; first electrical connection means for connecting a first end of the first conductive surface to a first zone of the ground plane; and second electrical connection means for connecting said first surface at least in the vicinity of the second end of the first conductive surface to a second zone of the ground plane that is distinct from the first zone; the assembly constituted by said first conductive surface, the portion of the ground plane electrically interconnecting the first and second zones, and the two connection means presenting an opening.
