Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an antenna array is used to increase antenna gain, then the directivity of the antenna is improved, but the signal loss of the feeding network is enlarged and the volume of the antenna is enlarged
Solution Approach 1:
The patent changes the physical and geometric parameters of the radome structure, including the shape, size, and arrangement of unit cells with C-shaped conductors. By optimizing these parameters, the radome enhances antenna gain through improved radiation characteristics while avoiding the signal loss issues associated with antenna arrays and their feeding networks
Solution Approach 2:
The radome acts as an intermediary structure between the antenna and the surrounding environment. The unit cells with C-shaped conductors serve as intermediate elements that manipulate electromagnetic wave propagation, achieving gain enhancement without requiring additional antenna elements or complex feeding networks
2Reliability
If an antenna array is used to increase antenna gain, then the directivity of the antenna is improved, but the volume of the antenna is enlarged
Solution Approach 1:
The patent optimizes the geometric parameters of the radome unit cells and their arrangement to achieve gain enhancement within a compact volume. The C-shaped conductor configuration and unit cell dimensions are specifically designed to provide the desired electromagnetic effects without requiring the large physical footprint of an antenna array
Solution Approach 2:
The unit cells with C-shaped conductors are arranged in a nested or compact configuration on the radome surface, allowing the gain-enhancing structure to be integrated within a small volume without requiring the extensive space needed for traditional antenna arrays
