I simulated a PIFA antenna in a tissue and obtain the following results but now,thess are my question :
- I'm not familar with IEEEC95.3 standar,dose my 1-g SAR result satisfy this standard?Which SAR calculations is important :Maximum SAR or average SAR?

Hi, 1g Average SAR is more important than unaveraged SAR.
1) Thermal effect is related to 1g average.
2) There is singularity from numerical simulation. So the peak SAR point is not necessarily worst heating location.
