Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the traditional design method of integrating and adjusting parameters of the entire array is used, then the antenna array can meet design index requirements, but the computing resources consumption increases and design efficiency decreases
Solution Approach 1:
The patent segments the antenna array design into independent modules: radiation elements with their feed networks are designed separately using reflection coefficient criteria, then assembled into the complete array. This modular approach allows each module to be optimized independently, reducing the computational complexity of adjusting the entire array parameters simultaneously while maintaining design index requirements.
2Manufacturing precision
If more computing resources are allocated for parameter adjustment, then the design accuracy can be improved, but the computing time cost increases
Solution Approach 1:
The patent performs preliminary design of radiation elements and power dividers separately using reflection coefficient criteria before assembling the complete array. This preliminary action establishes optimal parameters for each module independently, eliminating the need for extensive iterative adjustments of the entire array later, thus reducing computing time while maintaining design accuracy.
