Device micro - waves of the type with a slot line - a photonic forbidden bands

摘要

The present invention relates to a micro - waves of the slot line type - with a structure with photonic forbidden bands (beep), comprising at least: - a first substrate (10) in a dielectric material having a first permittivity εr1, - a second substrate (11) in a dielectric material having a second permittivity εr2 and - a conductive layer (12) between the two substrates, in which is etched at least one line - slot (13), -, with, on the face of the first and second substrates opposite the face in contact with the conductive layer, facing the slot line -, of the patterns (14,15) metallic périodiques.l' invention makes it possible to carry out a filtering structure compact.
