Very Short Microwaves problem

Consider the matching circuit in the figure below used to match an access transmission line with the characteristic impedance: Zc-50 Ohms to a load impedance: Z= 100-j100 Ohms,
The circuit is working at a frequency f=3.5 GHz. Imposing a maximum magnitude for the reflection coefficient at the input |S11=0.1, determine the bandwidth for each case. Discuss the results.
