A multi-curvature antenna comprises a radiation conductor and a support element. The outer rim of the radiation conductor is fabricated into an outer ring having an arc-shape surface, and the arc-shape surface has a notch. The central portion of the radiation conductor is patterned to form a conduction path. The support element carries the radiation conductor. A method for fabricating a multi-curvature antenna comprises providing a plane metallic sheet; pressing or stamping the metallic sheet to form a radiation conductor having an outer ring with an arc-shape surface; pattering the central portion of the radiation conductor into a predetermined conduction path and punching the outer ring to form a connection member; and cutting off the connection member to complete a multi-curvature antenna.
