So let's do a small theoretical review on antenna polarization. First of all, the polarization of an antenna refers to the orientation of the electric field (E-plane) of the radio wave with respect to the Earth's surface. Usually antennas are linearly (horizontally, vertically) or circularly polarized. Cross polarization ratio is a ratio of the copolar component of the specified polarization compared to the orthogonal cross-polar component over the sector or beamwidth angle. Simply speaking, cross polarization ratio is how much wave polarization coincides with an antenna polarization. |
