Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-system integrated antennas face limitations in achieving high gain due to the limited number of array elements, which restricts their performance and size, making it difficult to realize a high-gain antenna within a single radome.
Innovation Solution
The solution involves positioning the first antenna arrays and base station antenna arrays at different ends of a reflective plate, with base station antenna array elements enclosing intelligent antenna array elements, allowing for additional base station antenna elements to be added without increasing the radome size, thereby enhancing antenna gain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the number of array elements is increased to improve antenna gain, then the antenna gain is improved, but the radome size and reflective plate size must be increased
Solution Approach 1:
The patent embeds base station antenna array elements within the gaps between intelligent antenna array elements. Specifically, base station antenna elements are positioned in the spaces between adjacent intelligent antenna elements, allowing one antenna system to be nested within the structure of another without increasing the overall radome volume. This nesting approach enables increased total element count while maintaining the same physical footprint.
Solution Approach 2:
The patent utilizes the vertical dimension and three-dimensional space within the existing radome structure more effectively. By arranging intelligent antenna elements in a planar array and embedding base station elements in the gaps between them (both horizontally and vertically), the design transforms a two-dimensional layout into a three-dimensional configuration, maximizing space utilization without expanding the radome boundaries.
2Power
If the number of array elements is increased to improve antenna gain, then the antenna gain is improved, but the device complexity increases
Solution Approach 1:
The patent divides the antenna system into two distinct functional segments: intelligent antenna arrays for one frequency band and base station antenna arrays for another frequency band. Each segment operates independently with its own element configuration, allowing for modular design and simplified analysis. The intelligent antenna elements are arranged in columns, while base station elements are embedded in the gaps, creating clearly defined segments that can be designed and optimized separately.
Solution Approach 2:
The patent creates a multi-functional antenna system where a single radome structure supports both intelligent antenna functionality and base station antenna functionality simultaneously. The same reflective plate serves both antenna systems, and the embedded configuration allows both types of elements to coexist in the same physical space, reducing overall system complexity compared to having separate antenna systems.
