Abstract
Embodiments relate to a device for correcting the polarization twist of two linearly polarized signals using two polarization converters connected in series, wherein the second polarization converter can be rotated about an axis. In this way, the skew angle of an antenna can be compensated with respect to a satellite using a rotatable waveguide circuit. By converting the polarization from linear to circular, it is easier to rotate the now circularly polarized signals, using a second polarization converter, which reestablishes a linear polarization for the circularly polarized signals. Given the dual-channel signal outcoupling, the PCU may allow two orthogonal linear polarizations to be corrected at the same time using a simpler mechanical composition.
