Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional phased antenna arrays are used, then high gain and directionality are achieved, but narrow beamwidth and linear polarization restrict application versatility
Solution Approach 1:
The antenna array is divided into multiple independent antenna elements arranged in a grid pattern, where each element can be individually controlled and adjusted. This segmentation allows independent optimization of different regions of the antenna array to achieve both narrow beamwidth for high gain and adjustable polarization for versatility in wireless network applications
Solution Approach 2:
The patent implements dynamic beamforming capabilities through electronic phase shifters and amplitude controllers that allow real-time adjustment of beam direction, width, and polarization. This dynamic control enables the antenna system to adapt to different application requirements without physical reconfiguration, resolving the contradiction between fixed narrow beam characteristics and application versatility
2Adaptability or versatility
If multiple antenna elements are added to broaden application scope, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent designs a universal antenna element structure that can serve multiple functions through electronic control. Each antenna element is equipped with phase shifters and amplitude controllers that enable the same physical structure to perform different functions (different beam directions, different polarizations, different beamwidths) without requiring multiple specialized antenna structures, thus increasing adaptability while controlling complexity

AI summary
A multi-stack phased antenna array system is provided for enhancing wireless signal performance in a network. The system includes at least two antenna element layers, each comprising a matrix of individual antenna elements. Each antenna element is electrically connected to a modular ratio combining engine configured to process signals across the array. A method of operation includes receiving at least one signal from at least one user equipment (UE) at the antenna array, wherein the signal is received by each antenna element. The received signals are adjusted in time and phase to maximize in-phase signal strength using the combining engine. At least one dielectric layer is disposed between the antenna element layers to support the stacked structure.
