am working on circular polarized antenna on CST and need to check the axial ratio of the antenna. In post processing Far Field, there is an option to calculate the axial ratio. The problem is that what options should be selected to calculate the AR. Screenshot is attached for your info.

Select the Far Field monitor for the antenna in question. In the monitor properties window, click on the "Post-processing" tab. Under the "Polarization" section, select "RHCP" or "LHCP" depending on the antenna's circular polarization. Under the "Calculation" section, select "Axial Ratio". Set the frequency range and angular resolution for the calculation. Click on "Calculate" to obtain the axial ratio.
To calculate the axial ratio (AR) of a circular polarized antenna in CST's post-processing Far Field module, you need to follow these steps:

1-From postprocessing menu
2-Results
3-Select farfield results form drag down menu
4- pop up menu select directivity
5- anothor pop up .. on the right drag down select axial ratio
6- Evalute
7- generated AR at single theta value not a sweep
....
Good luck
