Abstract

The excitation of a Substrate Integrated Waveguide (SIW) makes use of costly and complex structures. In this paper, two simple structures have been presented to validate our computing results. This is a step discontinuity added to the microstrip line to produce an impedance matching between the SIW line and the line. Based on a small approximation of reflection, design equations are deduced, which allowed an optimal dimensioning of the step discontinuity (L×W). This design strategy was tested by simulating several waveguides, and a good agreement between the optimal geometric parameters and the calculated values was obtained.

Keywords: siw transition small reflection approximation
