A stacked antenna is provided to reduce a resonant length by adopting a substrate made of a composite containing magnetic material and polymer resin or a high magnetic permeability layer installed to be adjacent to a conductive antenna pattern. A stacked antenna includes antenna structures(10) including a magnetic dielectric substrate having predetermined relative magnetic permeability and relative dielectric constant and a conductive antenna pattern(12) formed on the magnetic dielectric substrate, and a feeding part(13) formed on surface of the magnetic dielectric substrates of at least one of the antenna structures and electrically connected with the conductive antenna patterns of the antenna structures. The conductive antenna patterns on upper and lower ones of the stacked antenna structures are electrically connected together.
