hi,
I'm looking for best method for simulation of "UWB Antenna" including several patchs on a thick substrate and 2 coaxial feed line,except FDTD.
whether FIT method is suitable for this?
regards.
CST will be fine, but my experience is the accuracy is not that good. If it is only the S11 I suggest use of HFSS. But If you need the radiated pulses, use software in the time domain, CST or XFDTD (this is FDTD) will do.
