Abstract
The multi-band antennais provided with a dielectric having the three-layer structure obtained by stacking layers so as that a central dielectric layermade of a low dielectric constant material is sandwiched by lower and upper side dielectric layersmade of high dielectric constant materials, a fed elementformed between the central dielectric layerand the upper dielectric layerand its base end being connected to a feed point on a specified side face of the dielectric having the three-layer structure, a grounded parasitic elementformed between the central dielectric layerand the lower dielectric layerand its base end being grounded on a specified side face, wherein the fed elementand the grounded parasitic elementis formed from the base end to the open end by a element obtained by connecting a plurality of line conductors and folding at least around the side face opposite to the specified face.
