Abstract

Disclosed is a polarization electric adjustment apparatus for a satellite communication antenna. The polarization electric adjustment apparatus comprises a polarization adjuster and a servo transmission apparatus, wherein the polarization adjuster comprises a polarizer, a polarization probe, a dielectric cylinder, a probe rotary shaft and a polarizer block; the servo transmission apparatus comprises a polarization adjustment motor, a motor bracket, a transmission pinion and a transmission rack wheel; the polarization adjustment motor and the transmission pinion are supported by the motor bracket; the transmission rack wheel is meshed with the transmission pinion; the transmission rack wheel is arranged on the polarization adjuster to drive the probe rotary shaft and the polarization probe in the polarizer to rotate; the dielectric cylinder adopts a cylinder made from a polytetrafluoroethylene material, supports the polarization probe, and is fixed to the transmission rack wheel through the polarization rotary shaft; and the polarization rotary shaft and the dielectric cylinder in the interior of the polarizer are coaxially fixed.

Description

technical field [0001] The present invention relates to satellite communication antennas. Especially the electric adjustment mechanism of the polarization of the airborne satellite communication antenna. Background technique [0002] The polarization direction of the satellite communication antenna refers to the direction of the electric field intensity formed when the satellite communication antenna radiates. For satellite communication antennas that work in linear polarization, polarization adjustments are required due to changes in geographic location and satellite attitude. The traditional polarization adjustment method is to realize polarization adjustment through manual or motor-driven rotating feed source and feed network. This kind of polarization adjustment mechanism has relatively large geometric dimensions and rotational envelope dimensions, and is relatively heavy in weight. It is difficult to realize the miniaturization and weight reduction of the whole machin...
