Problems solved by technology

[0002] It is known that the satellite antenna is used to receive the signal transmitted by the satellite to the ground, and the frequency of the satellite signal has been increased from the KU frequency to the KA frequency, so it is more sensitive to the directivity of the antenna reception, which is caused by the antenna radiation of the KA frequency The beam width (Antenna Radiation Lobes Beamwidth) is relatively narrow, and in terms of the installation

Embodiment Construction

[0012] The foregoing and other technical contents, features and effects of the present invention will be clearly understood in the following detailed description of an embodiment with reference to the drawings.

[0013] refer to figure 1 and figure 2 One embodiment of the rotation angle fine-tuning mechanism of the present invention is applied to a satellite antenna 100, so that the satellite antenna 100 can be positioned on a base surface (not shown) such as a building exterior wall, a top floor, etc., for receiving a A signal transmitted by a satellite at a fixed position relative to the Earth. From the perspective of the overall structure of the satellite antenna 100 , it includes a signal receiving device 1 , a base frame 2 , a supporting frame 3 and a fine-tuning mechanism 4 .

[0014] The signal receiving device 1 includes a dish-shaped reflector 11 and a wave collector 12, which are designed for the characteristics of the wireless signal transmitted by the satellite....

Abstract

This invention relates to rotation angle micro-adjusting structure, which is connected to one rack and one base frame located on one base surface to connect one signal receiving device to form one satellite antenna and rotate around the first axis center for initial positioning. The micro-adjusting structure is composed of one pivoting unit and one adjusting unit, wherein, the pivoting unit forms one first axis parallel to the second axis; the adjusting unit comprises one screw bar, one fixing part relative to the bar and one mobile parts along screw bar length direction through screw bar.

Description

【Technical field】 [0001] The present invention relates to a rotation angle fine-tuning mechanism, in particular to a fine-tuning mechanism applied to a satellite antenna for fine-tuning the horizontal azimuth angle and / or vertical elevation angle. 【Background technique】 [0002] It is known that the satellite antenna is used to receive the signal transmitted by the satellite to the ground, and the frequency of the satellite signal has been increased from the KU frequency to the KA frequency, so it is more sensitive to the directivity of the antenna reception, which is caused by the antenna radiation of the KA frequency The beam width (Antenna Radiation Lobes Beamwidth) is relatively narrow, and in terms of the installation of the current satellite antenna, most of them are initially aligned and fine-tuned manually, but the existing satellite antenna is only designed with a rough adjustment mechanism, so Once the sensitivity of antenna directivity is required to be greatly im...
