Patent ID: 7825862

Claim:
An electronic device comprising: a casing with an internal surface and an external surface; and an antenna device, comprising: a surface antenna pattern, which is formed by film coating technology on the external surface of the casing of the electronic device for transceiving a wireless signal of a predetermined radiation frequency; a signal guiding passage comprising an electroplated through-hole passing through the casing from the external surface to the internal surface, the signal guiding passage having a signal feeding end at the external surface electrically connecting to the surface antenna pattern and a connecting end at the internal surface; and an antenna signal feeding line, which is electrically connected between the connecting end of the signal guiding passage and an antenna module of the electronic device for feeding the wireless signal transceived by the surface antenna pattern to the antenna module of the electronic device, wherein the surface antenna pattern is formed by film coating technology selected from the group of dip coating, electroplating and sputtering.
