Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna units are closely arranged to centralize electromagnetic wave energy for short-wavelength carriers, then signal transmission quality is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The antenna array is segmented into multiple antenna units with standardized waveguide structures. Each antenna unit includes a waveguide body with ridge pairs, a coupling substrate with coupling pads, and an antenna array substrate with patches. This segmentation allows for modular assembly while maintaining close arrangement for signal centralization, reducing overall device complexity through standardization.
Solution Approach 2:
The patent employs a nested multi-layer structure where the antenna array substrate with patches is positioned below the coupling substrate with coupling pads, which in turn is positioned below the waveguide body with ridge pairs. This nested arrangement enables compact integration of multiple functional layers, achieving close antenna spacing while managing structural complexity through hierarchical organization.
2Reliability
If antenna units are closely arranged to centralize electromagnetic wave energy, then signal transmission quality is improved, but heat dissipation ability deteriorates
Solution Approach 1:
The coupling substrate acts as an intermediary layer between the antenna array substrate and the waveguide body. This intermediate structure provides thermal management functionality by incorporating heat dissipation features while maintaining the close arrangement of antenna units for signal centralization. The coupling substrate mediates between the signal transmission requirements and heat dissipation needs.
3Productivity
If antenna units are closely arranged for short-wavelength carriers, then bandwidth is increased, but transmission loss increases
Solution Approach 1:
The patent employs parameter optimization in the waveguide structure, specifically using ridge pairs with specific dimensions and configurations within the waveguide body. The ridge pairs have optimized heights, widths, and spacing parameters that are tailored for short-wavelength carriers, enabling efficient signal transmission with reduced loss while maintaining the bandwidth benefits of close antenna arrangement.

AI summary
The present invention discloses a new dual polarized array waveguide antenna configured above a signal processing substrate and sequentially including an antenna array substrate, a coupling substrate and a waveguide body. The antenna array substrate includes a plurality of patches, each of which having a first coupling portion and a second coupling portion coupled to the signal processing substrate. The top surface of the coupling substrate includes a plurality of coupling pads corresponding to the patches, and each coupling pad is configured above an intersection area of the first coupling portion and the second coupling portion. The waveguide body includes a plurality of waveguide channels passing through the waveguide body and corresponding to the coupling pads. Each waveguide channel has a first ridge pair and a second ridge pair projecting from wall surfaces. Each of the first ridge pair and the second ridge pair has a tapered opening portion withdrawn toward the wall surface of the waveguide channel on an upper section of the waveguide channel. Accordingly, signal transmission quality is improved by the structural arrangement above.
