s11 feko

Hi everyone,
I'm using Feko v5.2 but have many troubles. In some cases, the result of S11 and VSWR are different. (I use Feko to simulate PIFA)
Can someone help me!
 

Re: Problem with Feko

Thanks EMscuba. But even in result, I see the difference between S11 and VSWR. What made such thing happen?
