In this work, substrate integrated waveguide (SIW) has been designed and analyzed using two parallel rows of rectangular conducting slots on dielectric substrate. Different operating parameters such as electric field, return losses and the transmission gain is evaluated taking air as dielectric material in-between the slots. The results are evaluated for frequency domain of 6 to 12 GHz. The design is studied theoretically followed by the finite-element method (FEM) based modelling for optimizing the geometrical dimensions of the SIW structure. The results obtained had shown that the transmission gain increases with the increase in frequency upto 9 GHz and the return loss is minimum for this frequency.

Keywords: Substrate Integrated Waveguide, Finite Element Method, Return Loss, Transmission Gain, Electric Field.
