problem in HFSS (axial ratio)

Hi,
have simulated patch antenna. Since it is corner truncated it should have circular polarisation. In papers circular polarisation is determined on the basis of axial ratio. They have the graph of axial ratio versus frequency. it would be of great help if you suggest how to determine the axial ratio or the circular polarisation in hfss.

Create a new 'Far fields report' in HFSS with the trace of Axial ratio. It is one of the categories directly available after simulating in HFSS.

Set your Primary sweep to frequency and in the 'Families' tab, set your theta and phi to whatever value you want.

A sample specification is shown below:
