Simulation and Obtaining S parameter of a three-stage binomial transformer

implement by using a microstrip line structure on a printed circuit board with a relative dielectric constant of 3.7.

We assume the thickness of the substrate is 2 mm. Assume The center frequency is at 1 GHz. design this three-stage transformer and perform the S11 simulation.
