" S11=0 when input is complex matched" . It's wrong.
You should distinguish between "complex match" and "transmission line match". They are NOT identical.
I'd like to show you an example:
Zs=25 Ohm, Zload=100 ohm, connected with a lamda/4 length lossless transmission line (Z0=50);
Obviously, Gamma_s or Gamma_L is not equal to 0;
but they are conjugate matching in any position of the transmission line.

Thanks!
