Antenna device for electronic device, e.g. portable personal computer, includes surface antenna pattern which is formed by film coating technology

摘要

An antenna device comprises a surface antenna pattern which is formed by film coating technology on the external surface (211) of the casing (21) of the electronic device for transceiving a wireless signal of a predetermined radiation frequency; a signal guiding passage (27) comprising a signal feeding end (27a) and a connecting end; and an antenna signal feeding line (26) for feeding the wireless signal to the antenna module of the electronic device. The film coating technology may comprise dip coating, electroplating and sputtering.
