Simulating 4D antenna array (time modulated array)

Recommended Posts

hello everyone

i would like to ask you if it is possible to simulate 4-D antenna array by using FEKO software. since 4-D antenna array uses time (off-on switches), time domain solution is needed.

can we use FDTD to simulate this 4-D antenna array ?

thank you

Hi again

is it possible to use a periodic function in time analysis in post feko?  because the time modulated linear array (TMLA) uses periodic sequences (on-off).

it means that I simulate the antenna array in large enough range of frequencies, then in post feko I use the required periodic function for each element. is that possible?  if not, I think you should do it possible in future versions of feko because it is so important in simulating TMLA.

Hi
This is possible and is exactly what time analysis in POSTFEKO does. The analysis is based on FFT/IFFT and thus the signal is inherently periodic (you can't avoid it).
