Substrate-Integrated-Waveguide Filters: Design, Measurements and Wave-based Modeling Procedure

The idea of this paper is to present feasibility study design of a complex substrate-integrated-waveguide (SIW) filter as well as the fabricated unit of the 6th order SIW filter for CubeSat Ka band transceiver application. The other equally important goal is to verify its wave-based digital model developed by an existing approach based on wave digital filter theory. That means to investigate the accuracy of developed digital models that one can implement to model a two-port structure and to simulate it using Simulink platform, as well as the effects of selected parameter values that affects digital models.
