Simulate my layout of patch antennas in IE3D and send me the graphs

hi everyone
i am unable to simulate my layouts of patch antennas (drawn using Zealand v 12..)because
the license registered to our college got elapsed..
so plz simulate my layouts and send me the graphs..
i need the graphs for S11 v/s freq.(0.9 - 1.6 GHz) for the 2 slot and 4 slot antennas
with different combinations of diodes present (ON ) and removed (OFF).

thanx in advance...

Here are the results.

hey, can u pls tel me how to design capacitance or diode in ie3d....my project is vey much similar to urs....i am designing dual band microstrip antenna with 4 slots and capacitors in the slots...Till now i hav not been able to design capacitors in ie3d..Pls help!
