thanks... yes.. i'm trying to study the effects of parameter change such as dielectric constant (and so loss tangent) without changing the geometry..
I will 1st be using IE3D software to get various results.. and then later on try to fabricate..
Since i will be keeping the geometry same and only change the dielectric constant (and loss tangent simultaneously) during simulations from IE3D, i think the centre frequency will change.. right ?
So while setting up the software for simulation in IE3D .. what should i enter in this field - "Highest Operating Frequency Used "
FOr the original case shown at the start of the thread, i used this Operating Frequency setting as 16GHz. BUt that was for 1 set of dielectric constant, width, length of patch etc..
but now.. since the dielectric constant will be changed, i assume "The Highest Operating Frequency" value should also change.. Because by changing the dielectric constant, i dont know for which frequency range (or centre frequency) will this new set of antenna paramters work.. Or is there any formula to calculate this ? OR i just randomly put 20GHz and simulate and see if the S11 curve goes below the -10dB value.. but this will be too tedious..
Thanks
