1. The problem statement, all variables and given/known data An antenna is modeled by a 40ohm resistor in parallel with a capacitor with Xc = -j25. The antenna is fed by a lossless 50ohm signal line 0.15 wavelengths long. Use a Smith Chart to find the input impedance to the transmission line. 2. Relevant equations 3. The attempt at a solution The solution is in the attached file but i dont understand it after obtaining the admittance.
