Vector Rotator Solves Satcom Antenna Skew (.PDF Download)

Successful operation of in-flight internet and entertainment services requires accurate polarization alignment of the satellite and receive antennas for linearly polarized signals. Typically, the polarization alignment of the satellite and transceiver is accomplished by an electromechanical device that either rotates the antenna feed or other spatially operated devices that rotate the received signal vector. As will be seen, it is possible to provide the same rotational adjustment by means of
