near field analysis in CST

hello
anyone can tell me how i can see the near field disribution of an antenna in CST and also how can i calculate SAR .
plz tell me step by step preocedure

Hi Ravi,
You can use field monitor for measuring H field . Near field is mainly due to magnetic coupling. H field will give you a measure of near field distribution.
I guess you will be using some kind of Loop antenna, you can measure the surface current and magnetic energy density. (using field monitors)
