Re: FFT and FDTD
Hi settmar
I means by rsistance real component of impedance
my curve for impedance (resistance and inductance) is very will at required
frequency 1800 MHz but at frequencies far from 1800MHz the rael part of impedance is negative
i used FDTD to obtain time domain values...
FFT and FDTD
Dear friends
I have a problem with FDTD
I used method FDTD to simulate Microstrip antenna by using matlab
The propagation of the Gaussian pulse is very will
But by using FFT , I noticed that :
1- The resistances at some frequencies are negative
2- The time domain results ( like...
