Patent ID: 7671809

Claim:
An antenna device, comprising: a substrate having a first surface and a second surface; an ion-implanted antenna pattern formed at a predetermined position of the substrate and formed by an Ion-implantation process for transceiving a wireless signal of a predetermined radiation frequency, wherein the substrate comprises at least one through hole communicating the second surface and a bottom surface of the ion-implanted antenna pattern; a signal conducting member with a first end connecting to the ion-implanted antenna pattern and a second end extended to the second surface of the substrate, wherein the signal conducting member comprises a coating of conductive material coated on an interior wall of the through hole; and an antenna signal feeding line connecting to the signal conducting member for feeding the wireless signal transceived by the ion-implanted antenna pattern through the signal conducting member, wherein the ion-implanted antenna pattern is electrically connected to an antenna module of an electronic device through the signal conducting member and the antenna signal feeding line.
