Axial Ratio: Which value means linear polarization

[flanello]

Which value of the axial ratio of an antenna indicates a linear polarized antenna?

 

[rfmw]

A high value.

 

[Alan0354]

Suppose to be infinity as \[AR=\frac {major\; axis}{minor \;axis}\]. In linear polarization, Minor axis is zero.

 

[flanello]

Yes, thanks for the information.
But at what value an antenna is called linear polarized?

Supposed to be infinity as the minor axis is zero.
