A modular multi-band antenna design featuring radiators mounted partially above windows in a frame, allowing for interchangeable inserts to create interleaved antenna arrays, reducing manufacturing costs and enabling flexible configuration of frequency ranges, with a support structure and radome for protection and efficient electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple frequency bands and radiators are integrated in limited space, then the antenna covers multiple frequency ranges, but the manufacturing complexity and cost increase
Solution Approach 1:
The antenna is divided into a frame structure with multiple radiators arranged in arrays, where each radiator or group of radiators can be independently manufactured and then assembled into the complete antenna system. This segmentation allows for simplified manufacturing of individual components while achieving multi-band coverage through their collective arrangement.
2Volume of moving object
If radiators are arranged in arrays with minimal spacing, then the antenna size is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
Radiators are pre-assembled into arrays or sub-structures with the required precise spacing before final integration into the antenna frame. This preliminary arrangement allows for quality control and precision verification at an intermediate stage, reducing the overall manufacturing precision burden while achieving compact dimensions.
3Adaptability or versatility
If highly integrated antenna solutions are implemented, then multi-band coverage is achieved, but the manufacturing cost increases
Solution Approach 1:
The antenna frame and radiator structures are designed with universal components that can serve multiple frequency bands simultaneously. The same basic radiator geometry and support structures are reused across different frequency ranges, eliminating the need for completely separate antenna systems for each band and thereby reducing manufacturing costs while maintaining multi-band capability.
