Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-sided antenna design is used, then the manufacturing process is simpler, but the antenna performance is degraded due to environmental reflections and limited flexibility in mounting
Solution Approach 1:
The ground plane is segmented into two separate ground planes positioned on opposite sides of the substrate. This segmentation allows each ground plane to independently manage electromagnetic reflections from different directions, improving overall antenna performance while maintaining a relatively simple manufacturing process using standard PCB techniques
Solution Approach 2:
The antenna design transitions from a single-sided configuration to a dual-sided configuration by adding a second ground plane on the opposite side of the substrate. This dimensional change provides mounting flexibility and reduces environmental reflections without significantly complicating the manufacturing process
2Reliability
If the antenna is designed for a specific environment, then the electrical performance is optimized for that environment, but the antenna requires redesign for different environments increasing time and cost
Solution Approach 1:
The dual-sided antenna design with ground planes on both sides of the substrate creates a universal antenna structure that can adapt to different mounting environments. The antenna maintains satisfactory electrical performance across various configurations without requiring redesign, as the dual ground planes can accommodate different environmental reflection conditions
3Adaptability or versatility
If ground planes are added on both sides of the substrate, then mounting flexibility and environmental adaptability are improved, but the device complexity increases
Solution Approach 1:
The dual ground planes are electrically connected through the substrate, merging them into a unified ground system. This combining approach provides the benefits of dual-sided grounding for flexibility and environmental adaptability while maintaining a relatively simple overall structure that doesn't significantly increase device complexity
