Abstract

PURPOSE:To increase both Q and magnetic permeability mu for application to the high frequency as well as to facilitate the manufacture by manufacturing the antenna core by forming it into a thin layer through the wet molding method and with burning in the furnace. CONSTITUTION:An appropriate amount of binder is mixed up with the magnetic powder and then kneaded through the stirrer, roller and the like. Then sheet-type or belt-type plate 11 is formed with a necessary thickness through roller 3 and others. As plate 11 can be cut off into an optional length, no proper arrangement is required for the metal molds. Furthermore, the dispersion is reduced for plate 11 because of its uniform thickness. The blanking formation is also possible for the plate, and thus a complicated shape can be obtained easily. With such formation and through burning in the furnace, an antenna core of a small thickness can be manufactured easily. As a result, both Q and mu can be increased for the antenna core which is used for the high frequency.
