A novel Ku-band polarization plane adjusting mechanism is studied in this paper.The polarization plane matching between the signal of antenna and the signal of satellite is realized by rotating the internal structure of the transceiver-receiver orthogonal mode coupler.The polarization plane adjusting mechanism has the advantages of compact size,wide rotation angle range,small servo motor driving rotation,solving the problem of power supply and signal cable winding of low noise amplifier,higher reliability of the signal and more compact and reasonable structure layout.The electrical index of the polarization plane adjusting mechanism is similar to that of other conventional polarization plane adjusting mechanism.It has been applied to many engineering projects,and its performance index has been fully verified,which has broad engineering application value.
