Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different types of radiating antennas are used to generate dual polarization radiation patterns, then the radiation pattern coverage is improved, but the device complexity and fine-tuning time increase
Solution Approach 1:
The patent combines two different types of radiating antennas (patch antenna and slot antenna) into a single integrated antenna structure. The antenna element includes both a patch portion and a slot portion that work together to generate radiation patterns in both vertical and horizontal polarization directions, eliminating the need for separate antennas and reducing overall device complexity
Solution Approach 2:
The integrated antenna structure serves multiple functions simultaneously - it generates radiation patterns in both vertical polarization direction (through the patch portion) and horizontal polarization direction (through the slot portion), making a single antenna element perform the work of what would traditionally require two separate antennas
2Manufacturing precision
If two different types of radiating antennas are used for dual polarization, then the radiation pattern quality is improved, but the fine-tuning time and cost increase
Solution Approach 1:
By merging the patch and slot antenna structures into a single integrated element, the patent reduces the number of components that require individual adjustment and matching. This integration simplifies the fine-tuning process while maintaining the quality of dual polarization radiation patterns
3Adaptability or versatility
If multiple radiating antennas are used to achieve dual polarization, then the polarization direction coverage is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges multiple antenna functions into a single manufactured component, reducing the total number of parts that need to be produced, assembled, and tested. This integration lowers manufacturing complexity and cost while achieving dual polarization coverage
Solution Approach 2:
The single antenna structure is designed to provide multiple polarization directions, making it a universal solution that replaces what would traditionally require multiple specialized antennas, thereby reducing overall manufacturing cost

Enables the generation of dual-polarization radiation patterns efficiently and cost-effectively by adjusting the angle between the radiating portions and the midline, reducing the need for multiple antennas and fine-tuning time.
Implementation Method 1
When a signal is provided by a signal source and fed into the at least one antenna array through the signal feeding line, the at least one antenna array generates a radiation pattern
Implementation Method 2
the at least one antenna array generates a radiation pattern. A polarization direction of the second radiation pattern is orthogonal to a polarization direction of the first radiation pattern
