According to the present invention, the radiator of a chip antenna has a single physical radiator structure, but is electrically formed of a plurality of partial radiators symmetrical with respect to a feed point, and radiation operations in high and low frequency bands are separately performed. Therefore, complementary operational characteristics that counteract external effects are implemented, so that, when part of a human body, such as the hand, affects one partial radiator on one side of the chip antenna, the other partial radiator on the other side thereof independently operates, thereby minimizing performance degradation originating from the outside of the antenna.
