Satellite Antenna LNBF Position Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In satellite communication systems, especially in multiple-satellites-on-one-dish configurations, accurate positioning of Low Noise Block Down-converters (LNBFs) on supporting arms is challenging, leading to suboptimal reception efficiency due to directional sensitivity and difficulty in adjusting relative positions between the dish antenna and LNBFs.
Innovation Solution
A position adjustment device comprising a holder and an axis rotation bracket with an arc slot and positioning elements, allowing the LNBF to rotate and adjust along a focal axis, enabling precise positioning of LNBFs for optimal signal reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the LNBF is fixed on the supporting arm, then the structure is simple and stable, but accurate positioning is difficult and reception efficiency degrades
Solution Approach 1:
The patent transforms the fixed LNBF structure into a dynamic adjustable structure. The LNBF is mounted on an adjustable bracket that can rotate around the focal axis and adjust along the arc slot, enabling dynamic positioning to achieve accurate alignment with the satellite signal while maintaining structural simplicity through standardized adjustment mechanisms.
Solution Approach 2:
The supporting arm structure is segmented into multiple independent adjustment components: a holder fixed on the supporting arm, an adjustable bracket with rotation capability around the focal axis, and positioning elements that can move along arc slots. This segmentation allows independent adjustment of each component to achieve precise positioning without overwhelming structural complexity.
2Adaptability or versatility
If multiple LNBFs are attached to the supporting arm, then coverage of multiple satellites is achieved, but relative position adjustment becomes challenging and overall reception efficiency is compromised
Solution Approach 1:
The patent designs a universal adjustable bracket structure that can be used for multiple LNBFs. Each LNBF is mounted on an identical bracket assembly with rotation capability and arc slot positioning, allowing standardized installation and adjustment for multiple satellites while maintaining precise relative positioning through consistent adjustment mechanisms across all LNBFs.
3Reliability
If the LNBF is fixed in position, then manufacturing and installation are simple, but optimization of signal reception is difficult
Solution Approach 1:
The patent incorporates self-adjustment capabilities into the LNBF mounting structure. The adjustable bracket with arc slot and positioning elements allows operators to easily optimize the LNBF position for maximum signal reception without requiring complex manufacturing or specialized installation procedures. The standardized adjustment mechanisms enable field optimization while maintaining manufacturing simplicity.

AI summary
A position adjustment device for a satellite antenna includes a holder fixed on a supporting arm of the satellite antenna, and an axis rotation bracket disposed to the holder. The holder has a first connecting part. The axis rotation bracket rotates around a focal axis of the satellite antenna and comprises a bracket body where a low noise block down-converter with integrated feed (LNBF) of the satellite antenna is fixed, an arc slot disposed to the bracket body wherein a circular center thereof is on the focal axis, and a first positioning element passing through the first connecting part and the arc slot, for connecting the axis rotation bracket to the holder, and positioning the holder and the axis rotation bracket along the arc slot relatively.
