In a polarization angle adjusting mechanism for an antenna apparatus constructed of a supporting base and a transmitter/receiver apparatus equipped with a primary antenna at a right end portion thereof formed in an integral form, the primary antenna being located at a focal portion of an antenna, the supporting base has a cylindrical bearing for receiving a rotation shaft of the transmitter/receiver apparatus at a left end portion thereof, and also a plurality of subdivided projections are provided on this shaft receiving plane along a circumferential direction. On the other hand, projections and grooves fitted to a plurality of projections provided on the supporting base, which can be inserted among these plural grooves, are provided in the circumferential surface of the rotation shaft of the transmitter/receiver apparatus. The rotation shaft is inserted into the supporting base and the transmitter/receiver apparatus is rotated, so that the projections are fitted to the grooves so as to mount the transmitter/receiver apparatus to the supporting base. Similarly, another supporting base is mounted on the right end portion of the transmitter/receiver apparatus. In this manner, the transmitter/receiver apparatus is rotated to thereby adjust the polarization angle.
