Index Terms— Antenna arrays, dual polarization antennas. I. INTRODUCTION Simulations and measurements have demonstrated an input isolation of 45 and 43 dB between the horizontal and vertical ports, respectively. For further improvement in the cross-polarization level, the image feed method is also implemented, and a 2 × 2-element array made up of designed elements with image configuration has been fabricated. Cross-polarization isolation from very small aperture terminals (VSATs) (1992-2002-2007) Scope This Recommendation provides cross-polarization isolation levels for linearly polarized very small aperture terminal (VSAT) antennas to be used as reference limits for the VSAT antennas cross-polar gain in the main beam angular region. The satellite operator will normally require you to rotate the RF feed horn to achieve at least 30dB of isolation during the commissioning process, this test is called CPI (Cross Polarisation Isolation).

6. To inspire confidence in the measurements made in steps 4 and 5, note that between the positions of maximum and minimum isolation, the AUT should have been rotated 90° and the relative phase should have changed by ±90°.

Cross polarization isolation

cross-polarization isolation — Svenska översättning - TechDico

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.
