METHOD OF INTERNAL ANTENNA FOR IMPROVING PERFORMANCE USING ADHESIVE LAYER

摘要

The present invention relates to a method of manufacturing an internal antenna for improving performance using an adhesive layer. According to the embodiment of the present invention, the method of manufacturing an internal antenna for improving performance using an adhesive layer includes a step of forming a metal plate; a step of forming a radiation molding plate; and a step of forming a radiator of a metal antenna pattern. [Reference numerals] (AA) Start; (BB) End; (S100) First step of forming a frame made of injection materials in a predetermined shape and a metal plate to process a radiator arranged on the surface of the frame; (S200) Second step of forming a radiation molding plate in which an adhesive layer is formed by coating a thermosetting adhesive belonging to any one group among an epoxy-based, phenoxy-based, polyamide-based, and polyurethane-based on one surface of the metal plate to have a thickness of 5-10 關m; (S300) Third step of drying the radiation molding plate in which the adhesive layer is formed at least one hour at 30-60°C; (S400) Fourth step of forming the radiator including a metal antenna pattern in which the adhesive layer is formed on the surface touching the frame surface by pressing the dried radiation molding plate; (S500) Fifth step of temporarily assembling the radiator including the metal antenna pattern in which the adhesive layer is formed on the surface touching the frame surface and the frame; (S600) Sixth step of forming a built-in antenna by combining the radiator and the frame in which are temporarily assembled at 80-120°C and under the pressure of 3-5 kgf within 5-10 seconds
