Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional antenna is attached to a transparent glass window, then the antenna can be installed on the window surface, but the aesthetic appearance is influenced and the antenna gain is reduced due to glass attenuation
Solution Approach 1:
The patent transitions from a single-layer antenna structure to a multi-layer configuration with first and second radiation parts positioned at different distances from the glass window. The first radiation part is attached to the window while the second radiation part extends outward, creating a three-dimensional structure that overcomes the two-dimensional limitation of traditional planar antennas on flat surfaces.
Solution Approach 2:
The antenna structure embeds multiple functional layers within each other: the first radiation part is positioned on the glass window surface, the second dielectric layer is placed over it, and the second radiation part is positioned on top of the second dielectric layer. This nested arrangement allows each layer to contribute to the overall radiation performance while maintaining a compact form factor.
2Ease of operation
If the antenna is closely attached to the glass window, then installation is simple, but the antenna cannot effectively radiate electromagnetic energy
Solution Approach 1:
The antenna is divided into two distinct radiation parts with different functions: the first radiation part serves as the primary radiating element attached to the glass, while the second radiation part acts as an additional radiating element that extends beyond the glass surface. This segmentation allows each part to be optimized for its specific role in the radiation process.
Solution Approach 2:
The second dielectric layer functions as an intermediary between the first and second radiation parts, providing electrical isolation and mechanical support. This intermediate layer enables the second radiation part to be positioned at an optimal distance from the glass window without direct attachment, thereby improving radiation efficiency while maintaining installation simplicity.
3Illumination intensity
If a transparent antenna design is implemented, then optical transmittance is improved, but structural complexity increases with dual substrate structure
Solution Approach 1:
Both the first and second dielectric layers serve multiple functions: they provide mechanical support for the radiation parts, maintain appropriate spacing between layers, and contribute to the overall transparency of the antenna structure. This multi-functionality reduces the need for additional specialized components, thereby managing complexity while achieving the desired optical and electromagnetic performance.
