Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the antenna size is reduced to maintain a small footprint, then the device compactness is improved, but the antenna performance and efficiency deteriorate
Solution Approach 1:
The antenna is divided into multiple radiator elements (first antenna radiator, second antenna radiator, third antenna radiator, fourth antenna radiator) with different lengths and orientations. Each radiator segment contributes to the overall performance, allowing the antenna to achieve wide bandwidth and high efficiency while maintaining a compact footprint through distributed radiation elements rather than a single large element.
Solution Approach 2:
The patent utilizes three-dimensional space by placing radiators on both the first surface and second surface of the substrate, with radiators extending in different directions (parallel and perpendicular orientations). This multi-dimensional arrangement allows the antenna to achieve equivalent performance to larger planar antennas while maintaining a small footprint through vertical and multi-directional element distribution.
2Volume of moving object
If the antenna size is reduced to maintain a small footprint, then the device compactness is improved, but the bandwidth deteriorates
Solution Approach 1:
Multiple radiator elements with different lengths (first length, second length, third length, fourth length) are employed, where each radiator is designed to resonate at different frequency ranges. The combination of these segmented radiators creates a wide overall bandwidth while each individual radiator maintains a compact size, resolving the contradiction between small footprint and wide bandwidth.
Solution Approach 2:
The antenna system performs multiple functions through its multi-radiator structure: each radiator can operate independently or in combination with others, enabling the antenna to cover wide frequency bands while maintaining compact dimensions. The alternating polarization capability further enhances versatility without requiring additional space.
3Volume of moving object
If the antenna size is reduced to maintain a small footprint, then the device compactness is improved, but the gain deteriorates
Solution Approach 1:
The patent combines multiple radiator elements (first, second, third, and fourth antenna radiators) with alternating polarizations into a single integrated antenna system. This merging of multiple radiation sources with different orientations creates constructive interference patterns that enhance overall gain, allowing the compact multi-element antenna to achieve gain levels comparable to or exceeding those of larger single-element antennas.
Solution Approach 2:
The antenna employs a composite structure combining radiators with different polarization orientations (parallel and perpendicular to the substrate surface) and different lengths on a single substrate. This composite arrangement allows the antenna to achieve high gain across multiple polarizations and frequency bands while maintaining a small footprint, as the combined radiation patterns reinforce each other.
