Antenna Radome Coupling Structure for Tolerance-Stable 5G Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of communication equipment in 5G systems leads to reduced spacing between the radome and antennas, causing increased sensitivity to radome tolerance, which affects antenna performance.
Innovation Solution
A coupling structure is introduced to compensate for radome tolerance by being positioned at a lower height than the antenna, connected to the radome, to maintain consistent antenna performance despite height variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the distance between radome and antenna is reduced for miniaturization, then equipment size is reduced, but antenna performance sensitivity increases due to radome tolerance
Solution Approach 1:
A coupling structure is introduced as an intermediary element positioned between the radome and the antenna. This coupling structure includes a first portion connected to the radome and a second portion connected to the antenna, allowing it to compensate for height variations of the radome and maintain stable antenna performance despite miniaturization-induced tolerance issues
2Ease of manufacture
If radome height varies due to tolerance, then manufacturing is easier, but antenna operating frequency and radiation characteristics deteriorate
Solution Approach 1:
The coupling structure is designed with a height that is preliminarily determined to be lower than or equal to the antenna height, enabling it to compensate for radome height variations before they affect antenna performance. This preliminary configuration allows the system to maintain stable operating frequencies despite manufacturing tolerances
3Reliability
If coupling structure height is increased to compensate for radome tolerance, then antenna performance stability improves, but device complexity increases
Solution Approach 1:
The coupling structure is designed with different portions having different functions: a first portion connected to the radome for compensating height variations, and a second portion connected to the antenna for maintaining stable performance. This local differentiation allows effective tolerance compensation without requiring the entire structure to be overly complex
