Engineering Contradiction Analysis
1Reliability
If high-performance dielectric materials and precision fabrication processes are used to support antenna elements, then antenna performance and transmission efficiency are improved, but manufacturing cost increases
Solution Approach 1:
The patent divides the antenna support structure into multiple layers (first support layer, second support layer, third support layer) with different materials optimized for different functions. The first support layer uses high-performance dielectric material for electrical performance, while the second and third layers use lower-cost materials for mechanical support, thereby reducing overall manufacturing cost while maintaining transmission efficiency.
Solution Approach 2:
Different regions of the antenna assembly use different materials based on their specific functional requirements. The first support layer in contact with antenna elements uses high-performance dielectric material for optimal electrical characteristics, while other layers use cost-effective materials, achieving local optimization of both performance and cost.
2Manufacturing precision
If certain fabrication processes are used to support antenna elements, then antenna performance is improved, but mechanical defects such as warping occur
Solution Approach 1:
The support structure is segmented into multiple layers with different materials, where the second support layer provides a stable mechanical foundation that prevents warping, while the first support layer maintains precise antenna geometry. This segmentation allows each layer to specialize in either mechanical stability or geometric precision.
Solution Approach 2:
The patent employs composite material construction with multiple support layers made from different materials. The combination of materials in the first, second, and third support layers creates a composite structure that simultaneously achieves manufacturing precision for antenna geometry and mechanical stability to prevent warping.
