Hello

I am working on circular antennas RHCP and LHCP . I use the 4nec2 to simulate my antennas but i think that 4nec2 can calculate correctly the axial ratio of antennas . Can confirm that and what is the alternative to calculate the circular axial ratio of antennas with 4nec2 . Thanks

Yes you can....and if you go to the 3D plot, you can plot out the axial ratio directly, as well as the sense.

 

Here's an output file from 4nec2. I've removed everything above this, which is all the excitation information. The far field pattern is where you want to begin.

 

 

if i understand the best axial ratio for circular antenna is 1 ....in this picture the axial ratio is very low ...

That is correct. Can you send me the input file?
