Design and Fabrication of

Substrate-Integrated

Waveguide (SIW) Filters

Using LTCC: Problem Formulation

• Introduce a new methodology of designing waveguide inductive strip filters

embedded in Low Temperature Co-fired Ceramic (LTCC)

• The design method of the filter was derived by applying the equivalent Tnetwork

of the inductive strip derived using the ‘Variation Principle’ to the

usual technique of the filter design

• Three-dimensional electromagnetic field modeling and simulation was carried

out using HFSS (High Frequency Structure Simulator)

• Fabrication of the designed filters using 9k7 and 951 green-tapes LT-Design and Fabrication of
