Polarization control device, integrated circuit and method for compensating phase mismatch

An integrated circuit for a polarization control device for compensating phase mismatch, wherein the polarization control device is operably couplable via at least two radio frequency (RF) feed paths to an antenna arrangement that comprises at least two orthogonally polarized antenna elements, the polarization control device operably coupleable to at least one variable phase shifter located on at least one RF feed path;

• wherein the integrated circuit comprises:
• processing module arranged to:
• receive and process a coupled amount of at least one first RF signal;
• determine a phase mismatch between the at least two RF feed paths to the antenna arrangement 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 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 polarized antenna elements, based on the determined phase mismatch and a desired polarization of the at least one second RF signal to be radiated from the antenna arrangement.

A method for compensating phase mismatch between a polarization control device (360) and an antenna arrangement couplable via at least two radio frequency (RF) feed paths, the method comprising:

• receiving and processing at least one first RF signal;
• determining a phase mismatch between the at least two RF feed paths to the antenna arrangement of the processed at least one first RF signal;
• and
• adjusting a phase shift to be applied to at least one second RF signal applied to the at least one feed path passing there through to the at least two orthogonally polarized antenna elements based on the determined phase mismatch and a desired polarization of the at least one second RF signal to be radiated from the antenna arrangement.
