1Adaptability or versatility

If conventional resonator elements are used with parameter adjustments, then the resonator can be manufactured with simple structure, but the phase change is limited to maximum 180°

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple resonator elements (first resonator, second resonator, third resonator) into a composite resonator structure. By merging these elements with different resonant frequencies and coupling mechanisms, the system achieves extended phase control beyond the 180° limitation of single resonators, while maintaining manageable structural complexity through systematic integration

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The composite resonator structure serves multiple functions: it provides both frequency selection and extended phase control capabilities. The first and second resonators handle different frequency ranges while the third resonator enables coupling and phase extension, making the single structure universally applicable for various filtering and phase control requirements

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the resonator structure is simplified for ease of manufacture, then manufacturing becomes easier, but the design freedom and phase shifting capability are reduced

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The composite resonator is segmented into distinct functional modules (first resonator, second resonator, third resonator, reference conductor) that can be independently designed and manufactured. This segmentation allows each component to be optimized separately for both performance and manufacturability, then assembled into the complete structure with high design freedom

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The third resonator acts as an intermediary element that magnetically or capacitively couples the first and second resonators to the reference conductor. This intermediary structure enables complex phase control functionality while maintaining ease of manufacture through standardized coupling mechanisms

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A composite resonator includes a first resonator extending in a first plane direction, a second resonator spaced apart from the first resonator in a first direction and extending in the first plane direction, a third resonator located between the first resonator and the second resonator in the first direction and configured to magnetically or capacitively connect to or electrically connect to each of the first resonator and the second resonator, and a reference conductor extending in the first plane direction, located between the first resonator and the second resonator in the first direction, and serving as a potential reference of the first resonator and the second resonator. The reference conductor surrounds at least a part of the third resonator in the first plane direction.
