Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of available modes for vortex waves is increased to improve channel capacity, then the physical dimensions of transmitting/receiving antennas must be increased, but this adversely affects the movement and maintenance of the communication system
Solution Approach 1:
The patent employs a nested uniform circle array structure where multiple smaller circle arrays are nested within a larger array framework. This nesting approach enables the antenna to generate high-order vortex waves with multiple modes while maintaining a compact overall physical dimension, thereby resolving the contradiction between channel capacity improvement and antenna size reduction
Solution Approach 2:
The antenna is divided into multiple uniform circle array segments, each capable of generating vortex waves with specific modes. By segmenting the array and controlling each segment independently through phase shifters, the system can synthesize high-order vortex waves with enhanced channel capacity while keeping individual segment dimensions small
