Transparent Antenna Layout for Display Visibility Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna devices are not suitable for placement at positions visible from the outside of a transparent cover of electronic apparatuses as it reduces the visibility of the display panel.
Innovation Solution
An antenna device with a transparent flexible substrate and transparent antenna element is positioned on the inner surface of a transparent cover, allowing visibility from the outside while maintaining functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional antenna device is placed at a position visible from the outside of a transparent cover, then the antenna can be positioned on the outer surface, but the visibility of the display panel is reduced
Solution Approach 1:
The antenna element is made transparent to match the transparent cover, allowing it to be positioned on the outer surface without reducing display visibility. The transparency of the antenna element makes it visually imperceptible while maintaining its electromagnetic wave transmission and reception functionality.
Solution Approach 2:
The antenna device uses a composite structure combining a transparent flexible substrate with a transparent antenna element. This composite material approach allows the antenna to be positioned on the outer surface of the transparent cover while maintaining both the antenna's functionality and the display's visibility through the transparent cover.
2Illumination intensity
If the antenna element is made transparent to maintain visibility, then the display panel remains visible, but the antenna element must be positioned on the outer surface where it may be exposed to environmental factors
Solution Approach 1:
The transparent antenna element is nested within the transparent cover structure, with the antenna element positioned on the outer surface but protected by the cover's integrated design. The flexible substrate allows the antenna to conform to the cover's shape while maintaining protection from environmental factors.
Solution Approach 2:
The antenna element is mounted on a flexible substrate that allows it to conform to the outer surface of the transparent cover. This flexible mounting approach enables the antenna to be positioned on the outer surface for optimal signal reception while the transparent cover provides environmental protection.
3Illumination intensity
If the antenna device is positioned on the inner surface of the transparent cover, then the display visibility is maintained, but the antenna may be affected by internal components
Solution Approach 1:
The flexible substrate allows the antenna element to dynamically conform to the inner surface of the transparent cover, optimizing its position for electromagnetic wave reception while maintaining display visibility. The flexibility enables adaptation to the specific geometric constraints of the device interior.
Solution Approach 2:
The antenna element's transparency parameter is changed to match the transparent cover, allowing it to be positioned on the inner surface without affecting display visibility. This parameter change enables the antenna to be integrated into the visible area while maintaining its electromagnetic functionality.
