vswr berechnen

Hi,

first calculate reflection coefficient

Gam=(z-z0)/(z+z0)

Then calculate VSWR as

VSWR=(1+mod(Gam))/(1-mod(Gam))

Use smith chart. Calculate the normalized impedance first. Mark the normalized impedance on the Smith chart. Then draw S (VSWR) circle. Then read the S value on the smith chart. R circles and S circles are tangential to each other.

I hope it helps.

can u pls tell me hw can i see smith chart in HFSS? means hw to locate ?


thnx!

I created a simple tool to calculate VSWR and other microwave useful parameters.
