PURPOSE: A PCB layout structure for a chip antenna and a chip antenna device using the same are provided to tune an antenna by controlling the area of an antenna conductive pattern. CONSTITUTION: An input port(110a) operates as a feeding line and an antenna radiator. One end of the input port is electrically connected to the ground area. A ground port(130a) is separated from the input port with a preset distance and operates as a ground line and an antenna radiator. One end of the ground port is electrically connected to the ground area. The other end of the ground port is off. The input port is parallel to the ground port.
