An antenna is provided to reduce a size of an embedded antenna by integrating an antenna pattern with other circuit patterns. An antenna includes a conductive radiating pattern, a parasitic element(260), and a sliding portion(230). The conductive radiating pattern is formed on an antenna board and connected to a feeding line. The parasitic element is formed on the antenna board and electrically isolated from the radiating pattern. The sliding portion is coupled with the board and is capable of being slid. When extended, the conductive sliding portion is electrically connected to the radiating pattern at a contact portion. A length of the sliding portion is adjusted in multiple steps.
