Transparent Antenna Asymmetric Reticulated Wire Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent antennas face a trade-off between light transmittance and wiring resistance, where increasing light transmittance decreases antenna performance, and improving antenna performance increases wiring resistance.
Innovation Solution
A transparent antenna with a ring-shaped antenna wire formed by a reticulated metal film, where the per unit length area of one extension part is larger than the other, efficiently lowers wiring resistance while maintaining sufficient light transmittance by optimizing the area of reticulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the opening regions of the conductor mesh layer are expanded to increase light transmittance, then light transmittance is improved, but wiring resistance increases and antenna performance decreases
Solution Approach 1:
The patent applies asymmetry by making the first extension part (extending along the direction of extension) have a larger per unit length area than the second extension part (extending along an intersecting direction). This asymmetric configuration allows the antenna wire to achieve lower wiring resistance through the larger first extension part while maintaining sufficient light transmittance through the smaller second extension part, thereby resolving the trade-off between light transmittance and antenna performance
2Reliability
If the boundary segments are widened to improve antenna performance, then wiring resistance is reduced, but the opening regions become smaller and light transmittance decreases
Solution Approach 1:
The patent applies local quality by creating different per unit length areas in different parts of the antenna wire. The first extension part has a larger per unit length area to reduce wiring resistance and improve antenna performance, while the second extension part has a smaller per unit length area to maintain larger opening regions and ensure sufficient light transmittance. This localized differentiation allows each part to optimize for its specific function

Function Achieved in This Case
The solution effectively reduces wiring resistance while ensuring sufficient light transmittance, enhancing the overall performance of the transparent antenna.
Implementation Method 1
the flow of an electric current through the ring-shaped antenna wire causes a magnetic field to be generated on the center side of the antenna wire by an electromagnetic induction effect

AI summary
Included is an antenna wire 21, formed by a reticulated metal film in a shape of a ring, which generates a magnetic field on a center side thereof. The antenna wire 21 has a first extension part 23 extending along a direction of extension of the antenna wire 21 and a second extension part 24 extending along a direction intersecting with the direction of extension. The antenna wire 21 is configured such that a per unit length area of the first extension part 23 is larger than a per unit length area of the second extension part 24.
