Thank you very much sir for your response.
But, a small query though.
If we make Re of conductivity to zero in basic parameters, it will make the whole ground plane to be a dielectric.
I want to only truncate some part of it making the infinite plane to finite
Like if you you see in the F-shaped antenna design we need the ground plane to be present only half way under the subtrate. How can i do that?
Added after 1 hours 42 minutes:
I just understood what you said sir.
sir this is creating prob at the time of simulation..they are saying that there is no ground plane as when i have changed the real part of ground =0 then it starts behaving as a dielectric...
so how to simulate..pls help me sir..its urgent
truto reply sir with in 24 hrs..

bt sir these is creating prob at the time of simulation...when we have changed the real part of ground plane to 0,it also stars behaving as a dielectric..and at the time of simulation,they are saying that there is no ground plane for port..so how to simulate\
pls help..its urgent
