=== What You Will Learn ===
In this tutorial, you will learn how to design and use microstrip lines and components. You will analyze a microstrip double-step and will utilize microstrip discontinuity models to improve the accuracy of your analysis. Then you will build and analyze a stepped-impedance microstrip lowpass filter based on a standard lumped LC filter design.
