Hello everybody

I am a little confused with the smith chart matching tool.

The source impedance is the impedance of an antenna (50 Ohms), the rectifier impedance is 20.043 +j222.779. (Zin = Vin/I_Probe1.i)








Am i doing something wrong ?

I was expecting something near to 50 Ohms to real part, and 0 to the imaginary part...
 


You are looking at normalized impedance values.

0.99616*50 = 49.808 Ohms

Uncheck the Normalize option at the top.

Click to expand...

I know that's the normalized impedance showed in smith chart tool.

My question is: why in my simulated circuit which the Zin(Impedance of the rectificator) is in the first image(Real and imaginary part) i dont get 50+j*0 but 25.506+j*13.420


My Circuit


Input Impedance



Thanks
