In this work, six antenna models based on substrate integrated waveguide (SIW) technology has been designed and analyzed to investigate the effect of via shapes on its operating parameters. Different parameters that have been evaluated in this paper are electric field, return losses and the transmission gain. The results were evaluated while selecting the frequency domain in-between 6 to 11 GHz. A sequential design steps were followed to design the finite-element method (FEM) based antenna models of the SIW structure. The results obtained had shown that the bandwidth and resonant frequency of the designed antennas remain static but the overall gain changes with the change in the shape of vias.

Keywords: Substrate integrated waveguide, insertion loss, operating bandwidth, antenna gain.
