MEFiSTo-3D Nova antenna simulation enquiry

Hey everyone,

I have been trying to simulate a simple rectangle patch antenna with MEFiSTO... but I am very unsure of how the structure should be set up...

I read the radiation pattern section in the manual.. the only info I got was I need to have 6 absorbing boundaries and the radiating object is placed inside the closed box.

So should I draw the substrate (1.6mm) with propagation medium - material in the centre of the box with perfect electric boundary at the bottom of the substrate for ground plane, and the rectangular patch with microstrip feed on top of the patch drawn with perfect electric boundary?

And the rest of the box are filled with air? and how should I set up the reference structure for s-parameter extraction?

I have read the tutorial and manual... but still need some help.. and with this set up.. it will require 87 mb memory requirement..but the Mefisto-3d nova version is only restricted to 16 mb... so can anyone tell me how to simulate a patch antenna with mefisto-3d nova within the 16 mb memory

any info about the set up details for rectangular patch antenna will be very much appreciated.

Thanks
