14. A method of manufacturing a wireless communications antenna, the method comprising:
-
forming crack lines arranged in one direction on a magnetic sheet by crushing the magnetic sheet to divide the magnetic sheet by crack lines; stacking the magnetic sheet with other magnetic sheets into layers; press-processing the stacked magnetic sheets; bonding a first substrate to a top surface of the stacked magnetic sheets and a second substrate to a bottom surface of the stacked magnetic sheets; and forming conductive vias configured to connect conductive patterns on the first substrate with conductive patterns on the second substrate. - View Dependent Claims (15, 16, 17, 18, 19, 20)
