Compare the results with the literature reference, On the design of planar microwave components using multilayer structures‚ÄĚ, by W. Schwab and W. Menzel, IEEE Trans. MTT, vol. 40, no. 1, Jan 1992, pp. 67-72, Fig 9.
Note: The measured data from the referenced article are in good agreement with the simulated results. Any differences are most likely due to uncertainties regarding the model dimensions or dielectric properties.
