This tool calculates the reflection coefficient based on the load impedance and characteristic impedance. There are two definitions of the reflection coefficient (S-parameter)—Power waves and Traveling waves (Pseudo waves)—and this tool supports both. If the characteristic impedance is a real number, the two values are identical. Note that if the characteristic impedance has an imaginary component, the two values will differ.
Power waves : Γ=(Z-Zo*)/(Z+Zo)
Traveling waves : Γ=(Z-Zo)/(Z+Zo)
Traveling waves : Γ=(Z-Zo)/(Z+Zo)
| Reflectance Coefficient | Re(Γ) + Im(Γ)i |
| Reflectance (Magnitude) | |Γ| |
| Reflection Coefficient (Phase) | [°] θ |
| Return Loss (S11) | [dB] |
| VSWR |
*September 9, 2020: In response to requests, we have added output for polar coordinates, return loss (S11), and VSWR.
