antenna axial ratio

Hello RF people,

I'm looking for the table (or plot or formula) linking the Antenna Axial Ratio and the related Cross Polarization level.

Thanks in advance.

axial ratio cross polarization

X=(|r|+1)/(|r|-1) * (|r|+1)/(|r|-1)

if r=3dB=0.707 ->X=34=15.3dB

where X is XPD ,r is ratio axial.
 

axial ratio calculation

Again on Axial Ratio topic:

I am looking for a table (or a graphic) putting in relationship the Axial Ratio with the Input ports Amplitude unbalancement.

Please, can you provide it?

Thanks in advance.
