Notes. The half width ( HW, minimum and maximum) at -3, -10, -20 dB, the full width half maximum (FWHM), the ellipticity (e), the rotation angle of the polarization ellipse ($\tau$), the main beam directivity ($\cal D$), the cross polar discrimination factor (XPD), the main beam depolarization parameter (d), and the spillover ($\cal S$) are reported.
