CASE OF ELECTRONIC DEVICE HAVING ANTENNA PATTERN FOR LOW FREQUENCY EMBEDED THEREIN, MOULD AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A case of an electronic device having an antenna pattern for low frequency embedded therein, a mold and a method for manufacturing the same are provided to solve weakness to receive low frequency without an external additional antenna. CONSTITUTION: A radiator frame(210) is inject-molded into a polymer composite which includes a magnetic material component. A radiation unit(220) is formed in one side(210a) of the radiator frame and includes a low frequency antenna pattern. A case frame is injection-molded upward the radiator frame The radiation unit is buried between the radiator frames A boundary part is interposed between the radiator frame and the case frame and includes a recessive groove in the inner side of the case frame.
