SLOT-LINE-TYPE MICROWAVE DEVICE WITH A PHOTONIC BAND GAP STRUCTURE

摘要

The invention relates to a slot-line-type microwave device with a photonic band gap structure (PBG), consisting of at least: a first substrate (10) which is made from a dielectric material having a first permittivity er1, a second substrate (11) which is made form a dielectric material having a second permittivity er2, and a conducting layer (12) which is disposed between the two substrates and in which at least one slot-line (13) is provided. In addition, periodic metal patterns (14, 15) are disposed on the face of the first and second substrates opposite that which is in contact with the conducting layer, facing the slot-line. The invention can be used to produce a compact filter structure.
