Abstract: A method for manufacturing a helix antenna. A ceramic cylinder including a central through hole, a first annular surface, and a second annular surface is provided. The first annular surface is opposite the second annular surface. The central through hole is between the first and second annular surfaces. A flexible printed circuit board with a metal feeding strip extending outside the flexible printed circuit board is provided. The flexible printed circuit board is swirled and attached to the circumferential surface of the ceramic cylinder.
