Antenna Module Combining for Higher Peak Gain Beamforming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small antenna modules used in wireless communication systems have relatively poor peak gain, which can lead to ineffective wireless communication and prevent user equipment (UE) from being admitted to a cell or network due to poor quality signaling.
Innovation Solution
Combining post-beamformed signals from multiple antenna modules at the baseband level to increase peak gain and quality of wireless communication, by aggregating signals from multiple antenna modules and adjusting beam weights to ensure signals are transmitted in a common direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If small antenna modules are used in wireless communication systems, then device size is reduced, but peak gain deteriorates
Solution Approach 1:
The patent combines post-beamformed signals from multiple antenna modules at the baseband level to achieve signal aggregation. This merging approach allows small antenna modules to collectively provide higher peak gain equivalent to larger antenna systems, resolving the contradiction between reduced device size and maintained power performance.
2Device complexity
If small antenna modules are used, then device complexity is reduced, but signal quality deteriorates
Solution Approach 1:
By aggregating post-beamformed signals from multiple antenna modules at the baseband level, the system maintains high signal quality despite using simpler, smaller antenna modules. The combining process preserves the beamforming benefits while achieving the signal quality of more complex larger antenna systems.
3Power
If multiple antenna modules are combined, then peak array gain is improved, but device complexity increases
Solution Approach 1:
The system performs beamforming at each antenna module before combining signals at the baseband level. This preliminary beamforming action at individual modules reduces the complexity of the subsequent combining operation, as the signals are already optimized for their respective directions before aggregation.
