Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Antenna arrays face size restrictions and challenges in accommodating multiple communication protocols and frequency bands, limiting their ability to achieve omni-directional performance across all required frequencies within a compact size.
Innovation Solution
The antenna array design incorporates interleaved antenna elements on reflectors and corners, with different frequency bands covered by variously sized antenna elements and reflectors arranged in specific patterns, allowing for increased density and omni-directional coverage within a smaller footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antenna elements for different frequency bands are arranged on reflector faces, then omni-directional coverage is improved, but antenna array size increases
Solution Approach 1:
The patent transitions from two-dimensional arrangement on reflector faces to three-dimensional arrangement by placing antenna elements at corner positions where reflectors meet. This vertical and spatial utilization allows additional frequency bands to be accommodated without increasing the horizontal footprint of the antenna array, thereby maintaining compact size while achieving multi-band omni-directional coverage.
Solution Approach 2:
Different regions of the antenna array are assigned different functions: reflector faces host antenna elements for certain frequency bands, while corner positions host antenna elements for other frequency bands. This spatial differentiation allows each location to be optimized for specific frequency ranges, achieving multi-band operation without requiring uniform expansion of the entire array structure.
2Area of stationary object
If antenna elements are densely packed to reduce size, then array compactness is improved, but radiation pattern quality deteriorates
Solution Approach 1:
By utilizing corner positions in three-dimensional space, the patent creates additional separation between antenna elements without increasing the overall footprint. This spatial distribution in multiple dimensions maintains adequate element spacing for proper radiation patterns while keeping the array compact in the horizontal plane.
