Modelling, Design and Parametric Considerations for Different Dielectric Materials on Substrate Integrated Waveguide
Authors: , , ,
Abstract: In this paper, the model of substrate integrated waveguide (SIW) has been analyzed and designed to investigate the effect of dielectric materials on its operating parameters. Parameters that have been evaluated in this work are electric field, return losses and the transmission gain. Printed circuit board (PCB), silicon (Si), Mica and polymethyl methacrylate (PMMA) are used as different dielectrics to evaluate the results in the frequency domain of 1 to 10 GHz. Design steps in an orderly manner were pursued for the optimization of geometrical dimensions followed by the finite-element method (FEM) based modeling of the SIW structure. The results obtained had shown that the maximum change in the electric field is observed for PMMA while the transmission gain increases with the increase in frequency upto 9.75 GHz and correspondingly the return loss is minimum at this frequency.
