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.
