The polarization component is arranged in the middle of the antenna pan, and polarization independent rotation can be realized. The azimuth adjusting device is fixed on the base of the antenna housing through the antenna fixing device.
Specifically, as shown in fig. 1 and 2, the azimuth adjusting device includes an azimuth shaft 1, an azimuth bearing 2, an azimuth bracket 3, an azimuth motor 4, and an azimuth pulley 5.

The existing communication satellite receiving antenna generally fixes the motor on the inner side of the main body bracket, which causes the torque of the motor to be not large enough and influences the natural vibration frequency. The present embodiment moves the fixed position of the azimuth motor 4 outward to the outside of the azimuth bracket 3, and can increase the driving torque of the azimuth motor 4 without changing the motor performance.
Preferably, the middle hole of the azimuth axis 1 is enlarged, and a large-size azimuth bearing 2 is correspondingly adopted, so that the azimuth cable can conveniently pass through the inner hole of the azimuth bearing 2.
Preferably, the longitudinal width of the azimuth support 3 is increased appropriately, so that the structural rigidity and natural frequency of the antenna are improved, and resonance is prevented.
Preferably, the control circuit board of the antenna is mounted on the azimuth support 3.

In addition to this, the pitch adjustment device may also include a pitch switch 25 and a pitch weight assembly 26.
In one embodiment of the present disclosure, the pitch assembly 8 is composed of a pitch bearing 12, a pitch shaft 13, and an antenna pan pitch support sheet metal 14.

The pitching belt wheel 10 can drive the pitching support metal plate 14 of the antenna pan to rotate through the pitching shaft 13 and the pitching bearing 12, so as to further drive the antenna pan 15 to rotate, and adjust the included angle between the antenna pan 15 and the horizontal plane.
In one embodiment of the present disclosure, the azimuth pulley 5 of the antenna is connected to the antenna chassis 16, and the azimuth motor 4 pulls the azimuth pulley 5 to rotate on the antenna chassis 16 through the azimuth timing belt 7. The antenna chassis 16 may be fixed to a radome base 19 of the antenna by three posts 17, so that the whole antenna main body structure is fixedly arranged. The main structure of the antenna is fixed by the three upright posts, so that the height of the azimuth support 3 can be reduced, the rigidity and the natural vibration frequency of the azimuth structure can be increased, and the resonance phenomenon is avoided.

Specifically, one end of a polarization shaft 20 is installed on a polarization base 23, and the other end penetrates through the center of the antenna pan 15 and is connected with a polarization feed source 29, a feed source sub-reflecting surface 30 and the like; the polarization bearing 21 is sleeved on the polarization shaft 20; the polarization motor 22 is fixed on the polarization base 23 through a motor base 27, and the polarization motor 22 is connected with the polarization synchronous belt wheel 23 and drives the polarization synchronous belt wheel 23 to rotate; the polarized synchronous pulley 23 is connected with the polarized bearing 21 through a polarized synchronous belt 28; when the polarization synchronous pulley 23 is driven by the polarization motor 22 to rotate, the polarization synchronous pulley 23 can drive the polarization bearing 21 and the polarization shaft 20 to rotate through the polarization synchronous belt 28, so that the polarization base 24 connected with the polarization shaft 20, the polarization motor 22 mounted on the polarization base, and other components rotate around the axis of the polarization shaft 20, that is, the antenna polarization assembly can rotate around the axis of the polarization shaft under the pulling of the polarization synchronous belt 28 through the polarization motor 22 and the polarization synchronous pulley 23.

The blind hole is adopted to replace a thread through hole commonly used in the prior art, so that the risk that the screw blocks the 360-degree rotation of the internal mechanism of the antenna due to the fact that the screw is too long when the fastening screw penetrates through the stainless steel fixing plate can be avoided.
In one embodiment of the present disclosure, when the 80-two-axis communication satellite receiving antenna works, the control circuit board 38 for controlling the movement of the antenna firstly locks the local position according to the GPS, then controls the angle of the polarization component to be rotated through the operation program, after the rotation of the polarization component is completed, the control circuit board 38 controls the azimuth motor 4 and the pitch motor 9 to respectively drive the azimuth adjusting device and the pitch adjusting device to correspondingly rotate to the specified position obtained through the operation to start receiving signals, and tracks the microwave signals in real time after receiving the maximum value of the microwave signals.
