Q$3)[3$ marks$]$ A load $Z_L=100+j20$ is connected to a $\frac{20}{{?}_0}V$ voltage generator having a generator impedance $Z_g=50$ using a $20$ cm air$-$spaced transmission line with the following parameters per unit length: $C=70P\frac{F}{m}$ and $L=393\mathrm{.}75n\frac{H}{m}.$ If the line is operating at $1$ GHz $,$ find:

a$)$

a$)$ The input impedance?

Ans: $q,$

b$)$ The sending$-$end $($input$)$ current?

Ans: $q,(0\mathrm{.}25$ mark$)$
