WebCross polar discrimination (XPD) is a measure of how polar an antenna element is and instead used measure the rejection of an orthogonally polarised transmission. Definition … WebCross-pol discrimination is the magnitude of the relative power of the cross-polarized pattern with respect to the co-polarized pattern at a given angle Cross-pol discrimination over the sector/beamwidth is the minimum value measured in a defined ± angular deviation from the main beam direction.
WebJun 19, 2024 · The cross-polarisation discrimination (XPD) is a crucial technical indicator to evaluate the performance of base station antennas following Ludwig's third definition []. Current technical standards, as set, e.g. by China Mobile Ltd call for XPD better than 20 dB at boresight and better than 10 dB within ± 60° of the main lobe.
