Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with transparent antennas, there is a challenge in maintaining antenna performance while preventing signal loss and visibility issues due to the absence of metal mesh lines in specific regions, particularly in high frequency bands and display areas.
Innovation Solution
The solution involves arranging metal mesh lines orthogonally in slot regions and dielectric areas within the antenna, along with dummy mesh lines, to enhance electrical characteristics and visibility, using a configuration that includes a feeder connected to a transmission line with metal mesh lines parallel to its boundary and orthogonal mesh lines in the slot region, and additional dummy lines to prevent surface current generation.

Engineering Contradiction Analysis
1Ease of manufacture
If metal mesh lines are not disposed at the slot region inside the antenna or the dielectric region outside the antenna, then the structure is simpler and manufacturing is easier, but there is signal loss in high frequency bands due to sudden disconnection of the metal mesh line
Solution Approach 1:
The antenna structure is divided into multiple regions: slot region, dielectric region, and antenna region. Metal mesh lines are selectively disposed in different regions with orthogonal orientations to maintain signal continuity while simplifying manufacturing in specific areas.
Solution Approach 2:
Different regions of the antenna have different metal mesh line configurations. The slot region has orthogonal metal mesh lines to prevent signal loss, while other regions may have different configurations optimized for their specific functions, allowing localized optimization of both performance and manufacturability.
2Ease of manufacture
If metal mesh lines are not disposed at the slot region inside the antenna or the dielectric region outside the antenna, then manufacturing is simpler, but visibility is reduced between regions where mesh lines are disposed and regions where they are not
Solution Approach 1:
The metal mesh lines in different regions are arranged asymmetrically with orthogonal orientations. This asymmetric arrangement maintains visual coherence across regions while allowing manufacturing simplification in specific areas, as the orthogonal pattern creates a consistent visual texture despite regional differences.
Solution Approach 2:
Each region has locally optimized metal mesh line configuration. The slot region uses orthogonal lines for signal continuity, while visibility is maintained through coordinated positioning and orientation that creates visual consistency across the entire antenna structure.
3Reliability
If metal mesh lines are arranged orthogonally in slot regions and dielectric areas, then electrical characteristics in high frequency bands are improved, but the device complexity increases
Solution Approach 1:
The antenna is segmented into functional regions with specific metal mesh line orientations. The orthogonal arrangement is applied specifically in slot regions where it provides maximum electrical benefit, while other regions use simpler configurations, reducing overall complexity while maintaining high-frequency performance.
Solution Approach 2:
Orthogonal metal mesh line arrangement is applied locally in slot regions and dielectric areas where it provides critical electrical characteristics, rather than uniformly across the entire antenna. This localized application optimizes electrical performance while minimizing the increase in device complexity.
