PROBLEM TO BE SOLVED: To provide a composite antenna having small external size and by which a desired feeding point impedance is easily obtained. SOLUTION: This composite antenna is constituted of plural nearly U-shaped folded antennas A, B corresponding to plural frequency bands, including main elements (11, 11 and 14) one end of which is a feeding point and sub-elements 13, 16 folded from the other end of the main elements and whose end open, wherein each of the main elements (11, 11 and 14) of the antennas A, B is integrated and the external size of the whole antenna is reduced. |
