METHOD OF MANUFACTURING FILM TYPE ANTENNA USING SPUTTERING PROCESS

摘要

A method of manufacturing a film type antenna using a sputtering process is provided to improve an electroconductivity and a radiation property by forming an antenna pattern without impurities by using a sputtering process at the time of forming the antenna pattern on a carrier film. A method of manufacturing a film type antenna includes the steps of: preparing a carrier film(21) made of an insulating polymer material(a); forming an antenna radiator(23) on at least one surface of the carrier film by a sputtering process or a deposition process(b); inserting the carrier film in which the antenna radiator is formed into a mold(24) of a mobile communication terminal case shape(c); and forming a mobile communication terminal case(29) integratedly coupled with the carrier film in which the antenna radiator is formed by inserting a molding material into the mold(d). The step of forming the antenna radiator includes the steps of: attaching a masking tape in which a desired radiator pattern is bored onto at least one surface of the carrier film; sputtering a surface of the carrier film to which the masking tape is attached with a metal constituting the radiator; and removing the masking tape from the carrier film.
