Thermal-Aware Antenna Selection for Stable Wireless Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with multiple antennas face communication quality degradation and reduced lifespan due to increasing antenna temperatures during operation, which can lead to premature component failure.
Innovation Solution
The electronic device selects and prioritizes antenna groups based on temperature and power gain, using those with lower temperatures and higher performance to prevent overheating and maintain communication quality, by determining temperature and power gain measurements and switching to alternative antenna groups if necessary.

Engineering Contradiction Analysis
1Reliability
If the electronic device uses one or more antennas continuously for wireless communication, then communication continuity is maintained, but antenna temperature increases which reduces component lifespan and degrades communication quality
Solution Approach 1:
The patent implements dynamic antenna selection by continuously monitoring temperature measurements from multiple antennas and switching between them based on current thermal conditions. The system dynamically adjusts which antenna is active, transitioning from static antenna usage to adaptive antenna selection that responds to real-time temperature changes, thereby preventing overheating while maintaining communication continuity.
Solution Approach 2:
The patent changes the operational parameters of the antenna system by introducing temperature as a selection criterion alongside traditional communication metrics. The system monitors temperature measurements and uses these parameter changes to determine antenna switching decisions, allowing the device to operate within safe thermal boundaries while maintaining communication performance.
2Temperature
If the electronic device monitors temperature and switches antennas frequently to prevent overheating, then thermal management is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent segments the antenna system into multiple independently monitorable units, each with its own temperature sensor and performance characteristics. This segmentation allows the system to evaluate individual antenna conditions and make targeted switching decisions rather than managing the entire antenna system as a single unit, thereby simplifying the thermal management process while maintaining effectiveness.

AI summary
An electronic device having multiple antenna groups for data communication may determine a temperature of a first antenna group and determine a power gain of a second antenna group. The electronic device may communicate using the second antenna group in response to determining that the temperature of the first antenna group exceeds a temperature threshold and the power gain of the second antenna group exceeds a gain threshold. In some embodiments, the electronic device may receive communication link preferences, determine an antenna group that is disposed outside of thermal hotspots of the electronic device, and determine a beam that enables the communication link preferences via the antenna group. The electronic device may then transmit or receive data via the antenna group by forming the beam.
