Abstract
A microwave device of the slot-line type with a photonic band gap structure, including at least: a first substrate in a dielectric material having a first permittivity ∈r1, a second substrate in a dielectric material having a second permittivity ∈r2, and between the two substrates, a conductive layer in which at least one slot-line is engraved, with, on the face of the first and second substrates opposite the face in contact with the conductive layer, facing the slot-line, periodic metal patterns. A compact filtering structure is realized.
Claims7
A microwave device of the slot-line type with a photonic band gap structure, comprising:
- a first substrate in a dielectric material having a first permittivity ∈r1,
- a second substrate in a dielectric material having a second permittivity ∈r2, different from the first permittivity ∈r1, and
- between the first and second substrates, a conductive layer in which at least one slot-line is engraved,
- with, first periodic metal patterns realized on the face of the first substrate opposite the face of the first substrate in contact with the conductive layer, and second periodic metal patterns realized on the face of the second substrate opposite the face of the second substrate in contact with the conductive layer, said first and second periodic metal patterns facing the at least one slot-line to realize said photonic band gap structure.
