Multi-band meander line antenna

摘要

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 a narrow wide and a wide part being placed on a side of the feeder line and having a wider width than the narrow wide 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 wide parts are impedance matching parts and the antenna elements are all placed in a slanting position relative to a length direction of the dielectric substrate.
