Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional antenna technology is used for high frequency bands, then device complexity is reduced, but RF signal loss increases dramatically
Solution Approach 1:
The patent transitions from conventional planar antenna structures to a three-dimensional configuration with radiation parts extending in multiple directions (first direction parallel to ground layer, second direction perpendicular to ground layer). This dimensional change enables the antenna to radiate effectively in high frequency bands by creating electromagnetic planes in multiple orientations, thereby reducing RF signal loss while managing the increased structural complexity through systematic spatial arrangement.
2Object-affected harmful factors
If separate electromagnetic shielding components are added, then electromagnetic isolation is improved, but device complexity increases
Solution Approach 1:
The patent integrates electromagnetic shielding functionality directly into the antenna structure by using the ground layer and radiation parts configuration to provide both radiation and shielding functions. The ground layer serves dual purposes as both a reference plane for radiation and as an electromagnetic shield, while the radiation parts themselves are positioned to create electromagnetic planes that provide isolation. This merging eliminates the need for separate shielding components while maintaining effective electromagnetic isolation.
3Reliability
If antenna gain is increased through special technologies, then communication quality is improved, but device complexity increases
Solution Approach 1:
The patent segments the antenna into multiple radiation parts (first radiation part, second radiation part, third radiation part) with distinct functions and orientations. Each radiation part is configured to provide electromagnetic planes in specific directions, allowing the antenna to achieve high gain and communication quality through distributed radiation rather than requiring concentrated high-power amplification. This segmentation enables effective high frequency communication while avoiding the need for complex power amplifier integration.
