An unknown termination with impedance ZT = RT + jXT is matched to a lossless coaxial cable (Z₀ = 50Ω) using a short-circuited parallel stub. The stub (Z₀ = 50Ω) is .0985λ long and is placed at distance d=0.3127λ from the termination.
Use the Smith chart to solve the following problems:
a) Determine the normalized and un-normalized input admittance of the stub.
