The formula to calculate the Reflection Coefficient (RC) is:
\[ RC = \frac{Zl - Zo}{Zl + Zo} \]
Where:
Let's say the load impedance (Zl) is 75 ohms and the characteristic impedance (Zo) is 50 ohms. Using the formula:
\[ RC = \frac{75 - 50}{75 + 50} \]
We get:
\[ RC \approx 0.20 \]
So, the reflection coefficient is approximately 0.20.
