PROBLEM TO BE SOLVED: To provide a folding antenna device which becomes compact when being carried, and can receive radio waves of a plurality of frequency bands when actually used as an antenna.SOLUTION: The folding antenna device includes a first housing 10 to which a first antenna 11 is attached, a second housing 20 to which a second antenna 21 is attached, and a hinge 30 which makes these two housings foldable. The first and/or second antenna takes two states, i.e., a state being housed in the housing, and a state elongated from the housing. Radio waves of the first frequency band are received in the housed state, and radio waves of the second frequency band can be received in the elongated state. |
