Help with feko simulation
hi,
i´m trying to simulate the folded patch antenna which is in attach. But i'm having 3+53j Ohms, so i'm not sure about what i'm doing wrong, i think could be maybe about the port! i have done a wire where i want to do the feed and then aplied a wire port on it...
Great!! yes youre rigth i have seen that, because in the box where substrate came said that epsilon is 5, FR4, but i have seen in sonnet library 4.9 and another places 4.7. I think the best should be Duroid which have epsilon 2.2, and lower loss, at least is what i have seen that is more used...
ok, i will see that chapter!!
But theres's a big problem i'm using sonnet lite, so its limitated to 14MB. So i have to see how resolve this problem!!
thanks a lot for your help :)
best regards,

Hi,
thanks for your quick response.
Yes i saw the examples, but I was in doubt about ground plane!! because i've done in practice this antenna and i had approximately 268 + j3,9, for ressonant frequency (2.42Ghz) so i was waiting have similar values with sonnet! since i´m not having i supose...
Hi everyone,
I´m trying to simulate a patch antenna, but i´m having problems because i dont know how to make the ground plane. I have done 3 dielectric layers: air, dielectric, air. But i´m not sure if this is the right way to do a finite ground plane! I will be really gratefull if anyone...
Hi everyone,
I'm simulating an microstrip antenna (attachment), with microstrip line feed, in feko software.
First i simulated the antenna in a infinite substrate, but right now i'm trying to do it in a finite one.
Its a substrate with dielectric constant = 5; height = 1.6mm.
But i'm having...
hi gamba007,
í´m having the same proble about the feed in finite subtrates. Could you send me your example please? my email is jmga9@hotmail.com!

Hi,
i'm working with microstrip antenna and i use Txline sortware to determine the line dimension, but in the software i have to put the constant dielectric. My question is i have to put the constant dielectric or the effective?
I hope anyone can help!!!
Best regards,

hi e_m_c thanks a lot for your answer!
I will try the software that you recommend me, and see what i can do, because i really need to use one. i have been trying to use Feko Lite but because of their limitations i'm having a lot of problems!!!
Best regards,

I would like a simulator for microstrip antennas! and i would like to have radiation pattern, current distribution, etc simulated.
I worked with 4nec2 to simulate a panel antenna, but i'm not sure if i could the same with microstrip!
Thanks for your help and will keep waiting for suggestions...
Hi everyone,
I wish someone advise me a antenna software simulation that was efficient and free! i have:
- Mstrip40
- Feko lite
- Sonnet lite
- CST microwave studio
- Zeland
Have any one work with some of the list? what do you think?
Thanks!!
Best regards,
Jmga9
