Dear all
First of all i have little experience with EM software and i will be very happy if you give me some guidelines and support.
Thanks in advance
Hello @Theodoros
1. It is difficult to know if constant current is required without knowing more about the specific antenna. You are welcome to attach the .cfx file so that we can check how you have set it up
2. You may also want to have a look at what is possible with the planar Greens function.
Hi For a constant current distribution, I would suggest that you try to model it with one or more impressed current sources (they have to be straight lines, so you will have to use a few to approximate the loop). In reality, the current won't be constant, but for a small enough loop, it will be approximately constant. If you are simply trying to model an infinitely small loop, rather use a magnetic dipole source.
Any further help or advice will require more info regarding what you are trying to do.

Dear JIF First of all i would like to thank you for the immediate response.
Until now the small circular loop model is the only solution that i can think. Theoretically speaking the circumference of the loop should be C<0.2λ but in FEKO in order to achieve a good result should be at least C<λ/100. (just for informative purpose). Do you have any idea how i can simulate 3 Cubes: 1st PEC,Dielectric, 2nd PEC; The structure (PEC, Diel, PEC) should be infinite along z-axis and in addition the second cube should be infinite to z and x-axis.
Are you talking about 3 cubes in one model? This sounds like a very weird model. For infinite structures there are only two options:
Both have limitations, so it really depends on what you are trying to model.

Here is the geometry. It is very simple but how the infinity should be declared. I would like to know the near, far field and the reflection coefficient.
