ABSTRACT:
A column antenna apparatus and a manufacturing method thereof are disclosed. This invention forms a metal layer with at least two spiral structures 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 at least two spiral structures. The metal layer is formed on the surface of the column body, and the at least two spiral structures are formed on the metal layer for increasing bandwidth of low frequency. Each spiral structure is formed by removing a part of the metal layer, and the column body is exposed via the at least two spiral structures.
