1. A multiple band antenna comprising:

  • a dielectric substrate; and

    a plurality of antenna elements being formed of each a conductor on a same face of the dielectric substrate and provided in a one-to-one correspondence with frequency bands to operate the frequency bands, wherein each of the antenna elements has an open end as one end and is connected at an opposite end to a feeder line and comprises a narrow part being placed on a side of the open end and formed by line with narrow width and a wide part being placed on a side of the feeder line and having a wider width than the narrow width of the narrow part, the narrow part is turned in order in substantially the same direction as a width direction of the wide part, to form a meander shape, and the antenna elements have the wide parts joined in one piece forming a predetermined angle with each other so as to share a part of the wide parts, the predetermined angle being between 5°

    or more and 50°

    or less, and the wide parts of each of the antenna elements functioning as an impedance matching part of the antenna elements.
