Embodiment Construction

[0038] In order to fully understand the technical content of the present invention, the technical solution of the present invention will be further introduced and illustrated below in conjunction with specific embodiments.

[0039]The specific structure of the first embodiment of the present invention is as Figure 3 to Figure 10 shown.

[0040] like image 3 and Figure 4 As shown, the mechanical automatic polarization adjustment device includes a conversion adjustment assembly 10 and a quadrature mode coupler 20 . The conversion adjustment component 10 is used to convert the electromagnetic wave signal from the transmitter from the coaxial line transmission into a standard waveguide and adjust its polarization angle. The orthogonal mode coupler 20 is used to decompose the electromagnetic wave with the adjusted polarization angle transmitted from the conversion adjustment component 10 into horizontal and vertical components and output them.

[0041] like Figure 5 and ...

Abstract

The invention relates to a mechanical automatic polarization regulating device and a satellite communication in motion antenna system. The regulating device comprises a conversion regulation module and an orthomode coupler. The conversion regulation module comprises a casing, a polarization probe for regulating a polarization angle and a motor which is electrically connected with a main control computer and used for controlling the polarization probe to rotate. The casing is provided with a circular waveguide communicated with the orthomode coupler and a rectangular waveguide for receiving electromagnetic wave signals transmitted by a transmitter, the polarization probe is fixed to an output shaft of the motor and arranged in the circular waveguide in the casing and penetrates the rectangular waveguide. The orthomode coupler and the conversion regulation module having functions of a polarization regulator and a coaxial waveguide switch are adopted, and the motor is adopted to control the polarization probe to rotate, so that the applicable range of the regulating device is expanded.

Description

technical field [0001] The mechanical automatic polarization adjustment device and the mobile communication antenna system of the present invention belong to the field of satellite mobile communication (ie, "mobile communication") in wireless communication systems, and are used to automatically adjust satellite mobile communication ground station antennas (ie, "mobile communication"). The polarization direction of the linearly polarized electromagnetic wave signal matches the polarization of the uplink / downlink signal of the satellite transponder, so that the mobile communication antenna can accurately track the satellite. Background technique [0002] Satellite communication is a radio communication in which artificial satellites are used as relay stations, and consists of two parts: satellites and earth stations. Generally, satellite communication systems are divided into two categories, one is fixed satellite communication system, which refers to the wireless communicatio...
