Calculating Return Loss, Vswr, And Reflection Coefficients
Return Loss - VSWR - Reflection Co-efficient
Reflection co-efficient Γ is related to VSWR by the following formula:
In turn, reflection co-efficient is related to Return loss (RL) by the following formula:
Once you have computed the Return loss, RL, VSWR can be arrived at by using the following formula:
Typical values for Γ, RL, and VSWR are given below:
Note: The above values are approximate only. Please check for yourself using appropriate formula.
