Satellite Antenna Pattern Adjustment for Signal Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The positions of satellites in operation vary over time, leading to a deterioration in signal reception quality if satellite signals are received using an invariable antenna pattern, resulting in suboptimal signal reception.
Innovation Solution
A satellite signal receiving apparatus comprising an antenna array with a main antenna and pattern adjustment antennas, controlled by a unit that calculates the average intensity of satellite signals and adjusts the antenna pattern's angle to maintain signal quality above a preset intensity by adjusting the coupling relationship between the main and pattern adjustment antennas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an invariable antenna pattern is used for receiving satellite signals, then the device complexity is reduced, but the signal reception quality deteriorates as satellite positions change over time
Solution Approach 1:
The patent applies the dynamics principle by making the antenna pattern adjustable rather than fixed. The antenna array includes a main antenna and multiple pattern adjustment antennas that can dynamically change their coupling relationships under control unit guidance, allowing the antenna pattern to adapt to varying satellite positions and maintain optimal signal reception quality
Solution Approach 2:
The patent implements parameter changes by modifying the coupling relationship parameters between the main antenna and pattern adjustment antennas. The control unit adjusts these coupling parameters based on satellite position information, thereby changing the antenna pattern characteristics to match the current satellite configuration and maintain high signal reception quality
2Reliability
If the antenna pattern is adjusted dynamically to track satellite positions, then the signal reception quality is improved, but the device complexity increases due to additional antennas and control mechanisms
Solution Approach 1:
The patent applies segmentation by dividing the antenna system into a main antenna and multiple independent pattern adjustment antennas. Each pattern adjustment antenna can be independently controlled to modify specific aspects of the overall antenna pattern, allowing for fine-grained adjustment without requiring complete system redesign
Solution Approach 2:
The pattern adjustment antennas serve multiple functions: they can individually adjust different portions of the antenna pattern, work in combination with the main antenna to create various beam shapes, and adapt to different satellite positions. This multi-functionality reduces the need for separate specialized components for each adjustment scenario

AI summary
A satellite signal receiving apparatus and an antenna pattern adjusting method thereof are provided. A coupling relationship between a main antenna and a plurality of pattern adjustment antennas is adjusted to thereby adjust an angle of the antenna pattern so that the average intensity of satellite signals attributed to target satellites and received by an antenna array is higher than a first preset intensity.
