MICROWAVE DEVICE OF THE LINE-SLIT TYPE WITH A PHOTONIC PROHIBITED BAND STRUCTURE

摘要

The present invention relates to a microwave device of the line-slot type with a photonic bandgap structure (BIP), comprising at least: a first substrate (10) made of a dielectric material having a first permittivity εr1; a second substrate (11) made of 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 to the face in contact with the conductive layer, opposite the line-slot, periodic metal patterns (14,15). The invention makes it possible to produce a compact filtering structure. / p
