Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with displays made of conductive materials, high-frequency signals can be disrupted due to the display's high straightness, leading to decreased antenna radiation performance.
Innovation Solution
The implementation of a dielectric layer with conductive mesh patterns on the display, where the mesh patterns are configured in shapes such as rhombus or hexagon to improve antenna radiation performance while maintaining light transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a mesh type dielectric layer is used on the display to maintain light transmittance, then light transmittance is improved, but sheet resistance of the metal surface is substantially increased, decreasing antenna radiation performance
Solution Approach 1:
The dielectric layer is segmented into a mesh type structure with conductive patterns rather than a continuous solid layer. This segmentation allows light to pass through the mesh openings while the conductive patterns maintain the necessary electrical properties for antenna operation, resolving the contradiction between light transmittance and radiation performance
Solution Approach 2:
The dielectric layer combines insulating material with conductive patterns (such as transparent conductive oxide or metal mesh) to create a composite structure. This composite material simultaneously provides dielectric properties for antenna operation and optical transparency for display visibility, addressing both requirements
2Reliability
If a dielectric layer is placed on the display to enable antenna operation, then antenna radiation performance is improved, but the complexity of the device structure is increased
Solution Approach 1:
The dielectric layer with conductive patterns serves multiple functions simultaneously: it acts as the antenna radiating element, provides dielectric support, maintains optical transparency, and enables touch sensing functionality. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity while improving antenna performance
Solution Approach 2:
The antenna structure is merged with the display structure by integrating the radiating elements directly into the dielectric layer of the display. This combination eliminates the need for separate antenna components and simplifies the overall device architecture while achieving the desired radiation performance
