Abstract
A column antenna apparatus and a manufacturing method thereof are disclosed. This invention forms a spiral metal layer on a column body. The column antenna apparatus can simplify the manufacturing process and enhance the yield rate. The column antenna apparatus includes a column body, a metal layer and a spiral structure. The metal layer is formed on the surface of the column body, and the spiral structure is formed on the metal layer. The spiral structure is implemented by removing part of the metal layer to form a pitch structure. The column body is exposed between the pitches. The column antenna apparatus can be applied to a single, dual, three or multi frequencies wireless communication device. Furthermore, the column antenna apparatus can be installed at outside of the wireless communication device to be an external antenna or at inside of the wireless communication device to be a built-in antenna.
