Hi,

I am trying to verify my calculation for reflection coefficient is correct, can you please check if I have done it right? I bit confused since I have two imaginary part.

Terminated Impedance (Zt) = 9.07373 + j0.0291736
Characteristic Impedance (Zo) = 6 - j127

Reflection Coefficient =

(9.07373 + j0.0291736) - (6 - j127) / (9.07373 + j0.0291736) + (6 - j127)

= 0.993317569 (after convert to rectangular)

and my VSWR is 298.2922646

Thanks for help.

Characteristic impedances with non-zero reactance are not very common. In these cases, the definition of reflection coefficient is slightly different from the one you have computed.

$\rho = \dfrac{Z_t-Z_0^*}{Z_t+Z_0}$

The symbol $\square^*$ indicates complex conjugate.
