天线制造方法和天线结构;METHOD FOR MANUFACTURING ANTENNA AND ANTENNA STRUCTURE

摘要

一种天线制造方法，包括下列步骤：提供一铁磁性材料贴片；形成穿透过该铁磁性材料贴片之至少一贯孔，其中该贯孔系连接于该铁磁性材料贴片之一第一表面和一第二表面之间；于该铁磁性材料贴片之该第一表面上、该第二表面上，以及该贯孔内形成一不导电油墨层；针对该不导电油墨层施行一置换制程，以于该不导电油墨层上形成一第一金属层；以及针对该第一金属层施行一增厚制程，以于该第一金属层上形成一第二金属层，其中该第一金属层和该第二金属层皆由该铁磁性材料贴片之该第一表面经过该贯孔延伸至该第二表面。; forming a via hole through the ferrite sheet, wherein the via hole is connected between a first surface and a second surface of the ferrite sheet; forming a nonconductive ink layer on the first surface and the second surface and in the via hole of the ferrite sheet; applying a displacement process to the nonconductive ink layer to form a first metal layer on the nonconductive ink layer; and applying a thickening process to the first metal layer to form a second metal layer on the first metal layer, wherein the first metal layer and the second metal layer both extend from the first surface through the via hole to the second surface of the ferrite sheet.
