ABSTRACT:
There is provided a laminated aperture antenna in which a conductor wall composing the antenna is composed of a plurality of through conductors disposed at predetermined intervals and a plurality of sub-conductor layers disposed between dielectric layers of a dielectric substrate so as to electrically connect the plurality of through conductors within the dielectric substrate formed by laminating dielectric layers, or in which a resonant space is formed by a space of the dielectric surrounded by the conductor wall composing the antenna formed as described above, a lower conductor layer electrically connected to that and an aperture of the upper conductor layer corresponding to the antenna conductor wall. There is also provided a multi-layered wiring board comprising such laminated aperture antenna. Such laminated aperture antenna may be miniaturized and thinned and may be readily fabricated by the conventional lamination technology.
