Ask for programming to simulate radiation pattern?

Hi,

I have developed FDTD programming to simulate E and H field, but I don't know how to simulate radiation pattern, anyone have programming based on FDTD technique to produce radiation pattern for patch antenna?

Thanks a lot!

You might go to check http://emlib.jpl.nasa.gov/

Well, conceptly it can be done by near field and far field transformation.
You can see the materials form any classic FDTD books. As for E plane and H plane, you only need to define an angle of radiation pattern you want to caculate such as fai=0 and fai=90

Thank you guys for response. I will try to work out:)

i have writen it. if u have complete hfss training material. u can change it with me.
