Hybrid Antenna Coverage Layout for Lower-Power 360° Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Active antenna arrays in communication systems require high power consumption and cost to cover a 360-degree area, necessitating a solution to reduce these while maintaining coverage.
Innovation Solution
A communication system incorporating both active and passive antenna sets, where active antenna arrays cover 120-degree areas and passive antenna subsets cover 45-degree areas, with non-overlapping coverage angles, allowing for flexible configuration and reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If active antenna arrays are used to cover 360 degrees, then coverage area is improved, but power consumption and cost increase
Solution Approach 1:
The patent divides the antenna system into active antenna arrays and passive antenna subsets. The active antenna arrays cover 120-degree areas while passive antenna subsets cover 45-degree areas, segmenting the coverage responsibility to reduce the number of active components needed for 360-degree coverage.
Solution Approach 2:
The patent employs passive antenna subsets that consume no power as complementary elements to the active antenna arrays. These passive subsets provide additional coverage areas without incurring the power consumption and cost associated with active antenna components.
2Area of stationary object
If active antenna arrays are used to cover 360 degrees, then coverage area is improved, but cost increases
Solution Approach 1:
The patent segments the antenna system into active and passive components, allowing the expensive active antenna arrays to cover only 120-degree areas while cheaper passive antenna subsets handle the remaining coverage areas, thereby reducing overall system cost.
Solution Approach 2:
The patent uses passive antenna subsets that have no power consumption and lower cost as supplementary coverage elements, replacing the need for additional expensive active antenna arrays to achieve 360-degree coverage.
3Use of energy by moving object
If passive antenna subsets are used, then power consumption is reduced, but coverage area may be limited
Solution Approach 1:
The patent merges active antenna arrays and passive antenna subsets into a unified communication system. The active antenna arrays provide coverage for 120-degree areas while passive antenna subsets provide coverage for 45-degree areas, and their coverage areas are coordinated to collectively achieve 360-degree coverage.
Solution Approach 2:
The patent segments the coverage responsibility between active and passive components, with active antenna arrays handling 120-degree sectors and passive antenna subsets handling 45-degree sectors, allowing the system to achieve comprehensive coverage while minimizing power consumption through the use of passive elements.
