The purpose of the present invention is to provide a multiband antenna, an antenna array, and a wireless device, whereby deterioration in radiation efficiency can be suppressed and same can be made more compact. This antenna has: a conductor reflection plate; a first antenna comprising a first antenna element and provided upon the conductor reflection plate; and a second antenna provided upon the conductor reflection plate, comprising a second antenna element having, as an electromagnetic resonance frequency therefor, a frequency different from the electromagnetic resonance frequency of the first antenna element provided in the first antenna. The first and second antenna elements comprise: a C-shaped conductor being a substantially C-shaped conductor having a split section formed therein such that part of an annular conductor is discontinued; and a conductor supply line electrically connected to one section out of both sections of the C-shaped conductor that face each other across the split section, said conductor supply line constituting an electrical circuit for supplying power to the C-shaped conductor. |
