Disclosed is an antenna having an antenna radiator formed by printing electrically conductive ink on a substrate. An antenna radiator according to an embodiment of the present invention is formed to the same thickness as a skin depth with respect to an operation frequency of the antenna. Therefore, an antenna can be fabricated using a small amount of electrically conductive ink while not reducing the gain of the antenna. Further, an antenna radiator according to another embodiment of the present invention is formed to the same thickness as a skin depth with respect to a predetermined frequency at a corresponding hot spot with respect to the frequency. Accordingly, an amount of electrically conductive ink used can be further reduced while maintaining the gain of the antenna.
