Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antenna designs are used for millimeter wave signals, then device complexity is reduced, but signal propagation efficiency and beamforming capabilities deteriorate
Solution Approach 1:
The waveguide structure is divided into multiple honeycomb-shaped cavities arranged in an array, where each cavity acts as an independent resonant element. This segmentation allows the system to handle millimeter wave signals more effectively while maintaining a manageable overall structure.
Solution Approach 2:
The honeycomb cavity waveguide integrates multiple functional elements within a compact structure - the cavities are nested within the waveguide body, and the entire assembly is integrated with the antenna element, creating a space-efficient design that improves signal propagation without excessive complexity.
2Adaptability or versatility
If honeycomb cavity waveguide structure is integrated with patch antenna, then beamforming capabilities are improved, but device complexity increases
Solution Approach 1:
The honeycomb cavity waveguide is merged with the patch antenna to form an integrated assembly where the waveguide face is flush with the antenna surface. This combination enables beamforming capabilities while reducing the number of separate components that would otherwise increase system complexity.
Solution Approach 2:
The honeycomb cavity waveguide structure serves multiple functions simultaneously - it guides millimeter wave signals, provides beamforming capability through its array configuration, and integrates with the antenna element. This multi-functionality reduces the need for separate components, thereby managing complexity while enhancing adaptability.
3Productivity
If millimeter wave signals are transmitted in 5G FR2, then data transmission speed is increased, but signal propagation losses increase
Solution Approach 1:
The honeycomb cavity structure is designed with specific geometric parameters (cavity size, spacing, and configuration) that are optimized for millimeter wave frequencies. These parameter changes enable the waveguide to efficiently guide 5G FR2 signals while minimizing propagation losses through resonant effects and reduced radiation losses.
