Solution Overview
Problem
The insulation layer in existing electromagnetic wave adjusting devices, such as those using liquid crystal antennas, limits the capacitance adjustment range due to its placement between conductive elements, affecting the device's performance.
Innovation Solution
The electromagnetic wave adjusting device includes a first substrate, a first conductive element, a first insulation layer, a second substrate, a second conductive element, a dielectric layer, and a first conductive layer, where the first conductive layer is electrically connected to the first conductive element on the insulation layer, and at least part of it is disposed in the capacitance adjustable area, enhancing the capacitance adjustment range by reducing the distance between conductive layers on either side of the dielectric layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an insulation layer is disposed between conductive elements to provide electrical insulation, then insulation performance is improved, but the capacitance adjustment range is limited
Solution Approach 1:
The insulation structure is segmented into two parts: a first insulation layer disposed between the first and second conductive elements, and a second insulation layer disposed between the first conductive layer and the second conductive element. This segmentation allows the first insulation layer to provide necessary electrical insulation while the second insulation layer enables extended capacitance adjustment range, resolving the contradiction between insulation performance and capacitance adjustability.
Solution Approach 2:
The patent introduces a vertical stacking dimension by disposing the first conductive layer on the first insulation layer, which is itself disposed on the first conductive element. This multi-layer vertical structure allows the capacitance adjustable area to extend beyond the simple overlap area, thereby expanding the capacitance adjustment range while maintaining proper insulation through the layered configuration.
2Adaptability or versatility
If the distance between conductive layers is reduced to enhance capacitance adjustment, then capacitance adjustment range is improved, but insulation performance may deteriorate
Solution Approach 1:
The insulation function is segmented between two distinct insulation layers: the first insulation layer provides primary insulation between the first conductive element and the first conductive layer, while the second insulation layer provides insulation between the first conductive layer and the second conductive element. This segmentation enables reduced distance between conductive layers for enhanced capacitance adjustment while maintaining insulation performance through the distributed insulation structure.
