The antenna system integrates first and second support structures with specifically arranged first, second, and third antenna elements, along with switches controlled by transmission quality parameters, to provide selective diversity in a 4×4 or 2×2 MIMO configuration, allowing for optimal antenna element selection based on transmission quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna elements are integrated on support structures with specific arrangements, then transmission quality is improved through selective diversity, but device complexity increases
Solution Approach 1:
The antenna system is divided into multiple antenna elements (first, second, and third antenna elements) arranged on different support structures. This segmentation allows selective use of different antenna elements based on transmission quality requirements, improving reliability while managing complexity through modular organization.
Solution Approach 2:
The patent implements dynamic switching between different antenna elements based on transmission quality parameters. The system can dynamically select which antenna elements to use, adapting to changing environmental conditions and signal requirements, thereby improving transmission quality without permanently increasing operational complexity.
2Adaptability or versatility
If multiple antenna elements are arranged on support structures, then selective diversity is improved, but manufacturing complexity increases
Solution Approach 1:
The support structures serve multiple functions: they provide mechanical support for antenna elements, define the geometric arrangement of elements, and enable selective diversity. This multi-functionality reduces the need for additional specialized components, simplifying manufacturing despite the complex antenna arrangement.
Solution Approach 2:
Multiple antenna elements are combined on shared support structures rather than using separate mounting mechanisms for each element. This merging of functions reduces the total number of components and assembly steps, making manufacturing easier while maintaining the ability to selectively use different antenna elements.
3Productivity
If antenna system is enhanced for improved transmission efficiency, then product competitiveness is improved, but labor costs increase
Solution Approach 1:
The antenna elements and support structures are designed and pre-configured during the manufacturing process to enable future selective diversity operations. By preparing the structural framework in advance with all necessary mounting points and arrangements, the system achieves high transmission efficiency without requiring complex real-time adjustments or additional labor during operation.

AI summary
An antenna system comprises first and second support structures, and a plurality of first, second and third antenna elements. Each of the first and second support structures has four sides. Two adjacent sides are perpendicular to each other so that both the first and second support structures form a closed loop. The first support structure is disposed outside of and surrounds the second support structure. Some first antenna elements are disposed on two symmetric sides of the first support structure, and other first antenna elements are disposed on two symmetric sides of the second support structure. Some second antenna elements are disposed on another two symmetric sides of the first support structure, and the other first antenna elements are disposed on another two symmetric sides of the second support structure. The third antenna elements are disposed on the four sides of the second support structure.
