Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a patch antenna is designed to exhibit optimum radiation efficiency, then a specified height (or thickness) is required, but the mounting space height is limited making it difficult to implement an optimum lamination structure
Solution Approach 1:
The patent transitions from a conventional single-layer antenna structure to a multi-layer lamination structure, utilizing the vertical dimension (height) more effectively. By stacking multiple conductive patches and dielectric layers, the antenna achieves the required electrical height for optimal radiation efficiency while maintaining a compact overall form factor that fits within limited mounting space constraints.
Solution Approach 2:
The patent implements a nested lamination structure where multiple conductive patches and dielectric layers are stacked and integrated within a compact housing. Each layer is nested within the vertical space of the mounting area, allowing the antenna to achieve the necessary height for radiation efficiency while being contained within the limited overall height of the electronic device.
2Adaptability or versatility
If multiple antennas are included to cover different frequency bands, then communication capability is improved, but mounting space requirements increase
Solution Approach 1:
The patent designs a multi-layer antenna structure where different conductive patches and layer configurations serve multiple frequency bands simultaneously. The same physical antenna structure performs multiple functions by radiating and receiving signals across LB, HB, and other frequency bands, eliminating the need for separate dedicated antennas for each band and thereby reducing the total mounting space required.
Solution Approach 2:
The patent merges multiple antenna functions into a single integrated lamination structure. By combining multiple conductive patches, dielectric layers, and grounding structures into one unified antenna module, the design achieves coverage for multiple frequency bands while occupying a compact mounting area, rather than requiring separate physical antennas for each frequency band.
