<p>PROBLEM TO BE SOLVED: To provide a configuration of an antenna, that can realize a broadband resonance frequency in the contained state of the antenna and the improvement of an antenna gain in the extended state of the antenna at the same time, and to provide a mobile station using the antenna. SOLUTION: The antenna and the mobile station using the antenna are characterized in that the antenna is provided with a first antenna section, having a helical section and a first contact electrically connected to the helical section and with a second rod-shaped antenna section, whose one end is connected to the first contact and whose other end has a second contact. When the second antenna section is contained in an enclosure of the mobile station, the first contact reaches a state of opposing to a feeding section to be coupled capacitively with a matching circuit, and when the second antenna section is extracted from the enclosure, the second contact is in contact with the feeding section and directly coupled with the matching circuit.</p> |
