3D Distributed Antenna Beam Steering Without Mechanical Reorientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networking infrastructure, particularly for 5G, requires more precise control over the direction, polarization, and power level of electromagnetic radiation, which existing antenna systems struggle to achieve efficiently, especially in providing comprehensive radio coverage across wide angular regions.
Innovation Solution
A three-dimensional multiple-input multiple-output (MIMO) wireless system that integrates a sophisticated radiating structure capable of 360-degree azimuth and 60-degree elevation coverage, with multiple radios accessing a shared system, allowing for independent beam control by carrier frequency, polarization, and power level, and featuring a digital control logic for rapid beam re-direction and frequency translation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If physical reorientation of antenna mechanism is used to direct radiation pattern, then beam direction control is achieved, but mechanical inertia limits the agility of beam redirection
Solution Approach 1:
The patent replaces the mechanical reorientation system with an electronic phase control system. Instead of physically moving the antenna mechanism, the invention uses precise phase control among fixed antenna elements to redirect the beam electronically, eliminating mechanical inertia and achieving rapid beam steering.
Solution Approach 2:
The patent implements dynamic beam steering through electronic phase adjustment rather than static physical orientation. The phase control actuating elements can be rapidly reconfigured to change beam direction without mechanical movement, enabling agile and dynamic radiation pattern control.
2Speed
If precise phase control among fixed antenna elements is used to direct radiation pattern, then beam direction agility is improved, but control system complexity increases
Solution Approach 1:
The patent employs a universal phase control system that can direct radiation patterns in any desired direction within the coverage area. The same phase control mechanism handles both azimuth and elevation beam steering, providing multi-functional capability without requiring separate mechanical systems for each dimension.
3Adaptability or versatility
If fixed antenna elements are used to create directional radiation, then radiation confinement to narrow beam is achieved, but the system lacks adaptability to redirect beams rapidly
Solution Approach 1:
The patent makes the radiation pattern dynamic by enabling rapid electronic reconfiguration of phase control among fixed antenna elements. This allows the system to adapt beam direction quickly without physical movement, achieving both directional confinement and rapid adaptability.
