Sometimes, instead of considering the load impedance directly, you express its reflection coefficient, Γ L. We know the reflection coefficient Γ L is defined as the ratio between the reflected voltage wave and the incident voltage wave, as shown in Figure 1.

WebIf we want to get the values for a short circuit stub, we have already done all the work on the smith chart; we just need to read it from the open circuit side. Doing so you should simply get L1 = 0.128λ and L2 = 0.373λ. Series Stubs. In this example we will be matching a 75Ω line to a load that has an impedance of 90+j60Ω. Open Circuit: Web9 de jan. de 2024 · Smith Chart Question 1: Consider the following statements regarding the Smith's chart: 1. Smith's chart is a graphical indication of the impedance of a transmission line and of the corresponding reflection coefficient as one moves along the line. 2. λ distance on the line corresponds to a 720° movement on the Smith's chart.
