Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing electronic modulating devices are used, then basic modulation function is provided, but performance variation across different angles and frequency ranges is significant
Solution Approach 1:
The antenna is divided into multiple electrode groups (first, second, and third electrodes) with different areas, where each group is responsible for modulating electromagnetic waves in specific frequency ranges. This segmentation allows the antenna to maintain consistent performance across different frequency bands by assigning specialized electrode groups to different frequency ranges, thereby resolving the contradiction between reliability and adaptability.
Solution Approach 2:
Different electrode groups are designed with different areas to create local quality variations. The first, second, and third electrodes have progressively different areas, allowing each local region (electrode group) to optimize its modulation performance for specific frequency ranges. This local quality approach enables the antenna to achieve both performance consistency in each band and versatility across multiple bands.
2Adaptability or versatility
If a single electrode configuration is used, then device structure is simple, but modulation effectiveness across various frequencies is limited
Solution Approach 1:
The antenna structure achieves multi-functionality by incorporating multiple electrode groups that can collectively handle various frequency ranges. Each electrode group (first, second, third electrodes) serves multiple purposes: individual modulation for specific bands and collaborative modulation for broader frequency coverage. This universal design allows a single antenna structure to perform multiple frequency modulation functions without requiring separate antenna systems.
Solution Approach 2:
The electrode groups are arranged in a nested configuration where the first, second, and third electrodes are positioned relative to each other in overlapping or adjacent patterns. This nesting allows the electrode groups to share space efficiently while maintaining their individual modulation capabilities, thereby achieving frequency versatility without proportionally increasing device complexity.
3Power
If electrode areas are not differentiated, then manufacturing is simpler, but energy level difference between main and side lobes is insufficient
Solution Approach 1:
The patent applies parameter changes by varying the area of different electrode groups (first, second, and third electrodes) to optimize radiation characteristics. By adjusting the area parameters of each electrode group, the design achieves significant energy level differences between main lobes and side lobes, improving radiation efficiency and directional control. The different areas create distinct impedance characteristics that enhance the overall power output and beam shaping capability.
