Given the following load Z_L=25+j20 W, connected to a lossless transmission line of characteristic impedance Z_c=50 W and length d=0.150l.

• Find the load reflection coefficient.
• Find the load admittance.
• Find input impedance of the line
• Find the input reflection coefficent
• Find the input admittance

SOLUTION

First normalize the impedance z_L=Z_L/Z_c=(25+j20)/50=0.5+j0.4
