Non-uniform transmission line (Tapers) — Lesson 5

This lesson covers the concept of microwave integrated circuits, focusing on impedance matching networks known as tapers. It delves into the mathematical description of tapers, explaining how they are impedance matching networks with an infinite number of sections. The lesson also discusses how tapers can be physically implemented in microstrip lines, coaxial cables, and parallel plate waveguides. It further explores different types of tapers, including exponential, triangular, and Klopfenstein tapers, and their respective input reflection coefficients. The lesson concludes by highlighting the practical applications of tapers in microwave engineering and antenna design.
