Abstract
In this paper the Contour Integral (CI) method is applied to the design and analysis of substrate integrated waveguide (SIW) filters. This method is used for planar structures and is based upon the discretization of the boundary of the structure and needs less memory than full wave methods. For decreasing the computation time, circular vias replaced by square ones. A four pole Chebyshev X band dual inductive post substrate integrated waveguide filter is designed using this technique and the results are compared with measurements and simulation software Ansoft HFSS. Good agreement is seen between the results
