Abstract: A method for determining a state value of a traction battery of an electric vehicle characterises the ageing state, preferably an SoH value. The traction battery is charged or discharged by a test load and a respective output voltage and load current value pair is acquired. An ohmic internal resistance is established on the basis of the acquired value pair. The state value is established on the basis of the established ohmic internal resistance. At least one normalisation variable characterizing the traction battery is established. On the basis of the established ohmic internal resistance and the normalisation variable, a normalised internal resistance based on a reference value of the normalisation variable is established. The state value is established on the basis of the normalised internal resistance. A diagnostics device has an evaluation unit which is directly or indirectly couplable to the traction battery and carries out the method.

Abstract: The present disclosure relates to an antenna system for wireless communication of data. In one implementation, the system includes at least four horn antennas. Each horn antenna may have a three-layered cavity, and each layer may be filled with dielectric. The system may further include two microstrip line networks. The microstrip networks may be between two adjacent layered portions and configured to communicate with the horn antennas.

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.

At least one of the electrically-conductive layers is located between the first and second microstrip line networks.

At least one of the inner wall or the geometric constrictions has a stepped structure.

Given the dual-channel signal outcoupling, the PCU introduced here allows two orthogonal linear polarizations to be corrected at the same time using a relatively simple mechanical composition.
