Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional microstrip or circuit board antenna structures are used, then electromagnetic wave transmission capability is maintained, but structure complexity increases and processing difficulty increases at high frequencies
Solution Approach 1:
The antenna is divided into independent waveguide structures that can be separately fabricated and then assembled. Each waveguide structure operates as an independent radiation element, allowing modular manufacturing and reducing overall structural complexity while maintaining electromagnetic performance.
Solution Approach 2:
The feeding network is integrated directly with the waveguide structures by extending feeding lines into the waveguide cavities through notches. This merging eliminates the need for separate coupling structures and reduces the number of discrete components, thereby simplifying the overall antenna structure.
2Reliability
If traditional microstrip or circuit board antenna structures are used, then electromagnetic wave transmission capability is maintained, but processing convenience decreases at high frequencies
Solution Approach 1:
The antenna structure is segmented into discrete waveguide units that can be manufactured using standard waveguide fabrication techniques. These segments can be produced independently and then assembled, significantly improving processing convenience compared to monolithic high-frequency circuit board antennas.
Solution Approach 2:
The notch structure serves as an intermediary interface between the feeding network and the waveguide cavity. This intermediary design allows for easy connection and disconnection during assembly, greatly enhancing processing convenience while maintaining effective electromagnetic coupling.
3Reliability
If traditional microstrip or circuit board antenna structures are used, then electromagnetic wave transmission capability is maintained, but material consumption increases
Solution Approach 1:
By segmenting the antenna into discrete waveguide structures with specific cross-sectional dimensions, the total material volume is optimized. Each waveguide structure uses only the necessary amount of material for its function, reducing overall material consumption compared to traditional planar antenna designs that require extensive circuit board areas.
Solution Approach 2:
The antenna design transitions from two-dimensional planar structures to three-dimensional waveguide structures with optimized cross-sectional parameters. This parameter change allows for more efficient material utilization, achieving the required electromagnetic performance with less total material while reducing material consumption.
