Consider a transmission line of characteristic impedance Zc = 50 [0] terminated on a load having impedance Z. The signal frequency fo and the impedance load Z have the following: ZL=690[0], fo = 2370 [MHz] Design a single-stub matching network using the Smith Chart or transmission line equations, calculating the distance (in mm) d from the load and the stub length l; choose the solution with the minimum stub length. Fixed (d, l), calculate using MATLAB with ABCD matrices and Scattering matrices in the frequency range 0.2fo f 1.9fo the following parameters and plot all of them: 1) The scattering coefficients (modulus and phase) of the matching network (realized by the stub and transmission line between the stub and the load); make also a check on their correctness. 2) Modulus and phase of the reflection coefficient immediately on left of stub. 3) Real and imaginary part of the input impedance immediately on the left of the stub. 4) Real and imaginary part of the impedance immediately on the right of the stub. Assuming an incident voltage wave on the matching network (immediately left of the stub) of amplitude and phase V+ = 6e +j45* [V], plot: 5) Modulus and phase of the current at the input of the matching network (i.e. immediately on the left of the stub). 6) Modulus and phase of the current immediately on the right of the stub. 7) Reflected active power (real part of the mean complex power) and Transmitted active power normalized respect to the incident active power at the input of the matching network. 8) Repeat point 7) using a stub of length 1' = 1+ (c/2fo). 9) Modulus and phase of the voltage at a distance of 15 mm from the load. 10) Modulus and phase of the current at a distance of 15 mm from the load. 11) Active power at a distance of 15 mm from the load.
