Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single resonant frequency antenna is used, then the antenna structure is simple, but the frequency band coverage is limited
Solution Approach 1:
The antenna is divided into two independent resonant structures: a main antenna portion and an additional radiation element. Each portion can resonate at different frequencies, allowing the combined antenna to cover a broader frequency band while maintaining relatively simple individual structures
Solution Approach 2:
The antenna structure is designed to perform multiple functions by incorporating both a main antenna portion and an additional radiation element that can operate at different frequencies. This multi-functional design enables the antenna to serve multiple frequency bands without requiring separate antennas for each band
2Adaptability or versatility
If an additional radiation element is added to create multi-resonance, then the frequency band coverage is expanded, but the antenna structure becomes more complex
Solution Approach 1:
The main antenna portion and the additional radiation element are merged into a single integrated antenna structure. This combination allows both elements to work together to achieve multi-resonance and broaden the operating frequency range, while the merged structure reduces the need for separate antenna systems
Solution Approach 2:
The additional radiation element is positioned at a specific distance from the main antenna portion, creating a spatial arrangement that enables independent resonance while maintaining a compact overall structure. This dimensional positioning allows frequency diversification without proportionally increasing structural complexity

AI summary
A multi-resonant antenna comprises a main antenna and an additional radiation element. The main antenna comprises a main portion and a feeding portion. The main portion forms a split ring. The feeding portion extends outward of the main antenna from the main portion. The additional radiation element extends outward of the main antenna directly from the feeding portion.
