balaguru thavamani said:Axial Ratio will give the purity of Circular Polarization.
So with the help of axial ratio plot we can get an idea whether it is circularly polarised or not?
Ideal axial ratio plot will be within 1 dB but in pratical case up to 3 dB is accepted.

balaguru.

and practical upto 3dB is accepted.

Stutzman, Polarization in Electromagnetic Systems, Artech House, Inc., 1993.
It will explain what you need to understand about the various polarizations.

applies to every circular polarized antenna?
To check circular polarization in CST, i have to put 2 modes in waveguide port..after the simulation i combine results and i only see if is circular polarized in the farfield combined result? or simulating with only 1 mode, i can see if is circular polarized or not?
I´m bit confused, since the manual dont have much information about polarizations
thanks.
