Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multilayer patch antenna is constructed using additional dielectric carrier layers and support structures, then the antenna gain and bandwidth are improved, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The invention extracts and eliminates the complex dielectric carrier layer and additional support structure from the antenna construction. By directly attaching the upper patch surface to the lower patch antenna's radiation surface without these intermediate components, the patent simplifies the overall structure while maintaining the multilayer configuration that provides improved antenna gain and bandwidth.
Solution Approach 2:
The invention merges the upper patch surface directly with the lower patch antenna's radiation surface through direct attachment. This consolidation eliminates the need for separate dielectric carrier layers and support structures, reducing device complexity while preserving the beneficial multilayer antenna performance characteristics.
2Reliability
If commercially available patch antennas are upgraded to multilayer configurations, then electrical performance is enhanced, but the ease of manufacture deteriorates due to required structural modifications
Solution Approach 1:
The invention segments the antenna upgrade process into a simple two-component system: the commercially available lower patch antenna and the upper patch surface. By eliminating the need for complex structural modifications and additional dielectric layers, the patent makes the upgrade process straightforward and manufacturable while still achieving enhanced electrical performance.
Solution Approach 2:
The invention extracts and removes the complex dielectric carrier layer and support structure requirements from the upgrade process. This allows commercially available patch antennas to be enhanced to multilayer configurations through simple direct attachment of the upper patch surface, significantly improving ease of manufacture while maintaining enhanced electrical performance.
3Length of stationary object
If the upper patch surface is attached close to the radiation surface, then the antenna structure remains compact, but the longitudinal and transverse extension is limited
Solution Approach 1:
The invention extracts and eliminates the constraining dielectric carrier layer and support structures that previously limited the upper patch surface's extension. By using direct attachment, the patent allows the upper patch surface to achieve greater longitudinal and transverse extension without encountering the structural constraints of intermediate layers, while maintaining a relatively compact overall structure.
