11. A mold for manufacturing a case of an electronic device, the mold comprising:
-
upper and lower molds contacted with and supported by an radiator frame, the radiator frame injection molded so that a radiator including an antenna pattern part formed of a metal sheet is exposed on one surface of the radiator frame; a resin material inlet formed on at least one of the upper mold or the lower mold and having a resin material introduced thereinto so that a case frame shaped inner space formed by combining the upper and lower molds becomes a case frame; and a boundary part forming part provided to at least one of the upper mold or the lower mold and having the radiator frame inserted thereinto, wherein the boundary part forming part has an increasing inclination in a direction in which the resin material moves in the inner space. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of manufacturing a case of an electronic device, the method comprising:
-
forming a radiator including an antenna pattern part by pressing a metal sheet; injection molding a radiator frame to embed and expose the antenna pattern part in and on one surface of the radiator frame; allowing an outer circumferential surface of the radiator frame to be inserted into and seated in an inner side of a boundary part forming part formed in a mold of the case of the electronic device; and allowing a resin material to be introduced from an outer side of the boundary part forming part, pass through the boundary part forming part having an increasing inclination in a direction in which the resin material moves in the inner space, be introduced from an upper surface of the radiator frame and be then filled in a case frame shaped inner space formed in the mold of the case of the electronic device. - View Dependent Claims (24)
