EM-based parametric optimization of a transition from microstrip to substrate integrated waveguide interconnect
Description
An electromagnetics (EM)-based parametric optimization of a microstrip to substrate integrated waveguide (SIW) transition is described in this work. We study the waveguide length effects over the reflection coefficient in order to find a suitable SIW surrogate model. We perform a parametric optimization of this surrogate model. Finally, we simulate the original full-length SIW interconnect with microstrip transitions at the optimal surrogate model solution, confirming a significant improvement not only in the reflections but also in the transmission. Both the SIW interconnect and its surrogate model are simulated using a commercially available full-wave EM simulator.ITESO, A.C.
