Primärstrahler für Mehrstrahlantenne

摘要

When a converter is rotated via a rotation mechanism, the arrangement inclination angle of two primary radiators can be adjusted in the range of 0 to 20 deg with respect to an axis which is in parallel with the ground. Also the reception polarization angle due to probes of the primary radiators can be adjusted in the range of 0 to 20 deg while maintaining a preset difference in polarization angle among the satellites. Therefore, the arrangement inclination angle of the primary radiators for respectively receiving signals from the two satellites, and the reception polarization angle in the primary radiators can be simultaneously easily adjusted by rotating the converter via the rotation mechanism.
