Transmission Lines and Stubs
Part 1.
Go to the website:

and run the applet. See if you can calculate the VSWR when the load is 30 .
Part 2.
Go to the website:

Experiment with the simulator and see if you can predict the shape of the standing wave before
you move the reflection coefficient.
Experiment with the simulator and see if you can predict the shape of the standing wave before
you move the reflection coefficient.
What is the range of the SWR?
What is the significance of the center of the chart?
What assumptions are made about the transmission line?
What assumptions are made about the source?

a. Click the L-Network Matching and use the applet to solve Example 2.5 on page 59 of
Pozar. How do the two solutions provided by the applet compare to the results in the
book.
b. Click the Single Stub Matching and use the applet to solve Example 2.6 on page 62 of
Pozar. How do the solutions provided by the applet compare to the results in the book.
c. Using the MATLAB scripts used in class, perform one of the solutions for a and b,
above.
