Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dummy antenna element is added to improve radiation characteristics, then radiation characteristics are improved, but the number of components and production cost increase
Solution Approach 1:
A metal member is introduced as an intermediary element disposed between the outermost antenna elements and the ground conductor. This metal member acts as a mediator to improve radiation characteristics by optimizing the electromagnetic field distribution, thereby reducing the need for additional dummy antenna elements while maintaining or enhancing performance.
Solution Approach 2:
The invention changes the physical parameters of the antenna system by introducing a metal member with specific electrical conductivity and geometric properties. By adjusting the position, size, and material properties of this metal member, the radiation characteristics are optimized without increasing the number of antenna elements, thus resolving the contradiction between performance and complexity.
2Reliability
If a dummy antenna element is added to improve radiation characteristics, then radiation characteristics are improved, but production cost increases
Solution Approach 1:
The metal member is integrated with the existing ground conductor structure, merging two functional elements into a unified design. This integration allows the system to achieve improved radiation characteristics without adding separate dummy antenna elements, thereby reducing component count and production cost while maintaining manufacturing simplicity.
3Reliability
If the number of antenna elements is increased to improve radiation characteristics, then radiation characteristics are improved, but the difference in characteristics between outermost and center antenna elements increases
Solution Approach 1:
The metal member is strategically positioned adjacent to the ground conductors of the outermost antenna elements, providing localized electromagnetic field optimization. This local intervention equalizes the radiation characteristics between outermost and center antenna elements by compensating for the boundary effects experienced by outer elements, thereby achieving uniformity across the antenna array without increasing the number of elements.
