The scale works both ways. If the left side is axial ratio, then the right side is X-polarization or vice-versa. This is a quick video demonstrating cross polarization loss with linear and circular antennas.

For the full tutorial on polarization and other tutoria The following article serves to build an understanding about the antenna parameter known as Cross Polar Discrimination (XPD).

Rotate the AUT for maximum cross-polarization isolation and note the level (dB MAX).

This reduces the interference of your transmit signal on the opposite polarization that might be used by someone else. Cross-polarization discrimination (XPD) One measure to quantify the effects of polarization is called the cross-polarization discrimination (XPD) Cross-polarization discrimination observations - rain depolarization Looking at XPD as a function of the co-polar attenuation (A), it can be concluded that: XPD degrades at a given co-polar Axial ratio and cross polar discrimination (XPD) interference. For circular polarisation the purity of the polarisation is specified in terms of axial ratio.

High-isolation between main beams, high input isolation, and low cross-polarization level at broadside and scan angles up to 45 [7]. The beam mismatch should be within 5% of the beamwidth, the input isolation needs to be better than 40 dB, and the cross-polarization level needs to be lower than 20 dB and 40 dB for alternate and simultaneous transmission, respectively Cross-polarization isolation is determined using the modulated co-polarized signal component and the modulated cross-polarized signal component. The determined cross-polarization isolation can be used to adjust an antenna. Inventors: Downey, Michael L.

Disclosing this parameter is important as coupling between antenna ports can influence the Testing & Reporting Cross Polar Cross polarisation isolation or Cross Polarisation Discrinimation (XPD) is the difference in dB of received signal level (RSL) at the receiver when in turn, the transmitter has the same and Polarization 87 3.3.2 Incident Linear 45° Polarization 92 3.3.3 Procedure for Calculating the Rain Cross- Polarization Isolation or Discrimination Distribution 94 3.4 Numerical Analysis and Results 95 3.4.1 Analysis of Interpolation Technique 96 3.4.2 Analysis of Gauss-Hermite Quadrature Formula 97 Cross polarization (sometimes written X-pol, in antenna slang) is the polarization orthogonal to the polarization being discussed. For instance, if the fields from an antenna are meant to be horizontally polarized, the cross-polarization in this case is vertical polarization.

The OMT achieves 40-dB isolation and 35-dB cross polarization with the square waveguide antenna port. With the company’s long time serving mmWave bands, it’s well-poised for the coming requirements in automotive and 5G applications and offers many of the components not always considered as part of a passive component lineup, such as antennas.
