Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single element antenna designs in portable devices, such as laptops and smartphones, are limited in coverage and exhibit low gains at millimeter wave frequencies, particularly requiring an unobstructed line-of-sight for maximum efficiency and struggling with non-line-of-sight configurations.
Innovation Solution
Implementing an antenna array with dynamic polarization adjustment using interleaved horizontally and vertically polarized antenna elements, where a gradient optimization algorithm determines the optimal polarization for maximum power transfer, allowing for efficient LOS and NLOS wireless communication by selectively activating or deactivating antenna elements based on signal strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If single element antenna designs are used, then device size is reduced, but coverage and gain are limited at mm-wave frequencies
Solution Approach 1:
The patent divides the antenna system into multiple individual antenna elements arranged in an array configuration. Each element can be independently controlled and optimized, allowing the system to achieve higher gain and broader coverage while maintaining a compact form factor suitable for portable devices.
Solution Approach 2:
The patent combines multiple antenna elements into a unified array system with integrated control mechanisms. By merging the functionality of individual elements and implementing coordinated beamforming and polarization adjustment, the system achieves enhanced performance that exceeds the sum of individual elements.
2Device complexity
If fixed polarization antenna elements are used, then device complexity is reduced, but adaptability to different communication conditions is limited
Solution Approach 1:
The patent implements dynamic polarization adjustment capabilities where antenna elements can switch between different polarization states (horizontal, vertical, circular) based on communication conditions. This dynamic adaptability allows the system to optimize performance for LOS and NLOS scenarios without requiring complex mechanical structures.
Solution Approach 2:
The patent changes the operational parameters of antenna elements by adjusting polarization angles and activation states according to gradient optimization results. This parameter adaptation enables the system to respond to varying channel conditions while maintaining manageable device complexity through electronic control.
3Reliability
If all antenna elements are activated continuously, then coverage is maximized, but power consumption increases
Solution Approach 1:
The patent implements selective activation of antenna elements based on gradient optimization results and current communication needs. Instead of continuously activating all elements, the system activates only the necessary subset, reducing power consumption while maintaining adequate coverage through coordinated beamforming of active elements.
Solution Approach 2:
The patent employs feedback mechanisms where the system continuously monitors signal strength and channel conditions, then adjusts antenna element activation states accordingly. This closed-loop control ensures optimal coverage is maintained while minimizing power consumption by deactivating unnecessary elements in real-time.
