摘要：
A polarisation control device (360) for compensating phase mismatch, wherein the polarisation control device (360) is operably coupleable via at least two radio frequency (RF) feed paths to an antenna arrangement (219) that comprises at least two orthogonally polarised antenna elements. The polarisation control device (360) comprises or is operably coupleable to at least one variable phase shifter (420) located on at least one RF feed path. The polarisation control device (360) further comprises a processing module (490) configured to: receive and process at least one first RF signal; determine a relative phase mismatch between the at least two RF feed paths to the antenna arrangement (219) of the processed at least one first RF signal; and adjust a phase shift to be applied by the at least one variable phase shifter (420) for phase shifting at least one second RF signal applied to the at least one feed path passing there through to the at least two orthogonally polarised antenna elements, based on the determined relative phase mismatch and a desired polarisation of the at least one second RF signal to be radiated from the antenna arrangement (219).
