Antenna Radome Coupling Structure for 5G Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of antennas in 5G communication systems, due to technologies like massive MIMO, leads to reduced spacing between the radome and antennas, causing performance sensitivity issues due to radome tolerance, which affects antenna characteristics.
Innovation Solution
A coupling structure is deployed at a lower height than the antenna radiator, connected to the radome, to compensate for performance degradation caused by radome tolerance.

Engineering Contradiction Analysis
1Volume of moving object
If the distance between the radome and the antenna is reduced to accommodate more antennas, then the equipment size is minimized, but the antenna performance sensitivity increases due to radome deployment tolerance
Solution Approach 1:
A coupling structure is introduced as an intermediary component between the radome and the antenna. This coupling structure includes a coupling element that is physically connected to the radome and positioned at a height lower than or equal to the antenna height, serving as a mediator to compensate for radome deployment tolerance and maintain stable antenna performance
Solution Approach 2:
The coupling structure changes the height parameter of the radome system by providing a reference level that is lower than or equal to the antenna height. This parameter change allows the system to compensate for radome height variations and maintain consistent antenna-to-radome spacing despite manufacturing tolerances
2Reliability
If a coupling structure is added to compensate for radome tolerance, then antenna performance stability is improved, but device complexity increases
Solution Approach 1:
The coupling structure applies local quality by providing compensation only at the specific location where radome-to-antenna spacing is critical. The coupling element is positioned locally near the antenna and radome interface, affecting only the local spacing relationship rather than requiring global structural changes
