It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention, unless further departing from the spirit and scope of the invention as defined by the appended claims. It will be possible.
The present invention, in order to solve the problem, the terminal body, combined with the terminal body to cover a part of the terminal body, the rear cover is formed with an opening, the opening is inserted into the opening, glass fiber reinforced plastic sheet (GFRP Sheet: Glass Fiber) Provided is a mobile terminal having an antenna including a reinforced plastic sheet) and an antenna pattern formed on one surface of the glass fiber reinforced plastic.
The rear cover may be formed in an insert injection molding method integrally with the glass fiber reinforced plastic sheet.
The rear cover may further include a coating layer on the outer surface of the glass fiber reinforced plastic sheet.
The antenna pattern may be formed by printing a conductive nano ink.
According to another aspect of the present invention, there is provided a method of manufacturing a rear cover of a mobile terminal, printing an antenna pattern using a conductive nano ink on one surface of a glass fiber reinforced plastic sheet, and curing the glass fiber reinforced plastic sheet printed with the antenna pattern. (curing) and insert-molding the rear cover so that the glass fiber reinforced plastic sheet is inserted into the center.
After the insert injection molding step, it may further comprise the step of forming a coating layer on the outer surface of the rear cover and the glass fiber reinforced plastic sheet.
In addition, the curing may be carried out under the conditions of 120 ℃ to 200 ℃.
According to at least one of the embodiments of the present invention, by manufacturing the antenna integrally with the rear cover of the mobile terminal, it is possible to reduce the overall thickness by the thickness of the rear cover of the mobile terminal.
In addition, even if the rear cover is omitted, it is possible to reinforce the strength by using a glass fiber reinforced plastic sheet, it can be cured at a high temperature to cure the printed antenna pattern by using a glass fiber reinforced plastic sheet.
