Abstract

The invention relates to the technical field of communication antennas and provides a polarization feed source device and a satellite antenna device. The polarization feed source device comprises a polarization assembly and a rotating assembly sleeved at an outer side of the polarization assembly, wherein the rotating assembly comprises a fixing ring used for fixedly connected with a host machine,the polarization assembly is arranged in the fixing ring in a penetrating mode and rotates around the central axis of the fixing ring, and the polarization assembly rotates clockwise or anticlockwisearound the fixing ring to change the polarization direction of the polarization feed source device. The polarization feed source device is advantaged in that polarization direction adjusting operation difficulty is remarkably reduced, and polarization direction adjusting convenience is effectively improved.

Description

technical field [0001] The invention relates to the technical field of communication antennas, and in particular provides a polarization feed device and satellite antenna equipment. Background technique [0002] The polarization of an electromagnetic wave is the locus of the vector endpoints of the electric field at a given point as a function of time. The endpoint of the electric field moves along a circle, which is called a circularly polarized wave. In the circular polarization mode, it is divided into a left-handed polarization direction and a right-handed polarization direction. [0003] At present, in Ka-band satellite systems, circular polarization is generally used. When the satellite antenna equipment is sending and receiving satellite signals, it is necessary to adjust the polarization direction of the polarization feed device to be consistent with the polarization direction of the local satellite signal, that is, the circular polarization mode of the polarization...
