Antenna structure and manufacturing method thereof

The invention discloses an antenna structure and a manufacturing method thereof. The manufacturing method of the antenna structure comprises the following operations. And forming a plurality of through holes penetrating through the transparent substrate. An insulating layer is formed to cover the opposite upper and lower surfaces of the transparent substrate and the inner wall of the through hole. And forming a metal layer to cover the insulating layer and the through hole and fill the through hole. And forming a metal protection layer to cover the metal layer above the upper surface. The invention also provides an antenna structure, which adopts glass as the substrate, and has the advantages of low dielectric loss and improved substrate strength. 本发明公开一种天线结构及其制造方法，其中天线结构的制造方法包括以下操作。形成多个通孔贯穿透明基板。形成绝缘层覆盖透明基板的相对上表面和下表面以及通孔的内壁。形成金属层覆盖绝缘层及通孔并填满通孔。形成金属保护层覆盖上表面上方的金属层。本发明另提供一种天线结构，采用玻璃作为基板，具有低介电损耗及提高基板强度的优势。
