Patch antenna in IE3D

Please i have the following questions:
1- How can i remove a small rectangl from the patch antenna in IE3D?
2- How can i transfer the above resultant antenna to the MATLAB (i.e how can i transfer the structure from the IE3D to MATLAB, or if i draw a patch antenna using PDE tool of MATLAB how can i transfer it to IE3D).
3- How can i write a MATLAB code for the genetic algorithm to remove the rectangle from the patch antenna.

attached files you can find two useful thesis about IE3 and PSO.

http://www.mentor.com/electromagneti...ion/multimedia side help u.u find demo of ur requirement.

How can i generate a patch antenna in MATLAB and rempve selected conductive cells using genetic algorithm. And how can i export these data to IE3D?

patch antenna design can possible frist caculate w,l,h in matlab.then polar plot and returm loss calculation can done by simple formula u right.in ie3d manual help u lot for design
