You would like to measure the input impedance of your circuit with a 50 ohm network analyze.r At the frequency you are interested in you measure a reflection coefficient of 0.8-j0.4. What is the ...

A 100-Ω transmission line is connected to a load consisting of a 50-Ω resistor in series with a 10-pF capacitor. Find the reflection coefficient at the load for a 100-MHz signal. Source: Ulaby, F.
