Solution Overview
Problem
Split-ring resonators are difficult to arrange at locations other than the edge of a conductor due to short-circuiting issues when placed elsewhere, which hampers their functionality as an antenna.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a split-ring resonator is placed at a location other than the edge of a conductor, then the antenna design flexibility and radiation efficiency are improved, but the split-ring resonator cannot be properly arranged due to short-circuiting issues
Solution Approach 1:
The conductor is divided into multiple segments by introducing openings, which electrically isolates different regions. This segmentation prevents short-circuiting and allows split-ring resonators to be placed at non-edge locations without electrical interference, thereby improving arrangement feasibility while maintaining design flexibility
Solution Approach 2:
Openings are introduced as intermediary elements between the split-ring resonator and the conductor body. These openings act as electrical insulators that prevent short-circuiting, enabling the split-ring resonator to function properly at non-edge locations without direct electrical contact with the conductor
2Adaptability or versatility
If the opening size is made adjustable, then the frequency characteristics can be controlled, but the device complexity increases
Solution Approach 1:
The opening size is made dynamically adjustable rather than fixed, allowing the conductor's electrical characteristics to be changed in real-time. This dynamic adjustment capability enables frequency control of the split-ring resonator without requiring multiple different conductor designs, thus achieving adaptability with moderate complexity increase
Solution Approach 2:
The physical parameter of opening size is changed to control the electrical frequency characteristics of the split-ring resonator. By adjusting the opening dimension, the resonant frequency can be tuned, providing frequency control capability through a simple geometric parameter change rather than complex circuit modifications
