Transparent Mesh Antenna Layout for Dual-Polarization Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to design a dual polarization antenna that can operate in high-frequency communication bands without being visible to the user, especially in limited spaces where it may overlap with the display region of thin, high-transparency display devices, causing image quality deterioration.
Innovation Solution
The antenna element features a radiation body in a mesh structure with orthogonal transmission lines and signal pads formed in a solid structure, minimizing signal loss and visibility by positioning the radiation body and transmission lines in the visual region and signal pads in the non-visual region, with a ground pad and dummy pattern for improved performance.

Engineering Contradiction Analysis
1Productivity
If the radiation body is placed in the visual region to enable communication function, then the antenna can be embedded in limited space, but the antenna becomes visible and image quality deteriorates
Solution Approach 1:
The patent applies local quality by making different parts of the antenna have different structural characteristics. The radiation body uses a mesh structure with high transparency in the visual region, while the signal pads use a solid structure in the non-visual region. This allows the antenna to maintain communication functionality while being visually transparent in the display area.
Solution Approach 2:
The patent resolves the spatial conflict by separating components across different spatial dimensions - specifically by dividing the antenna element into a visual region and a non-visual region. The radiation body is positioned in the visual region with mesh structure for transparency, while signal pads are positioned in the non-visual region, effectively using spatial dimensionality to solve the visibility problem.
2Manufacturing precision
If the signal pad is formed in a bent shape with solid structure, then the manufacturing precision is improved, but the signal loss increases due to bending
Solution Approach 1:
The patent applies local quality by assigning different structural characteristics to different parts of the antenna. The signal pads are formed with a solid structure in the non-visual region to ensure easy manufacturing and good electrical connection, while the radiation body uses a mesh structure in the visual region to maintain transparency. This localized differentiation allows each part to optimize its own characteristics without compromising the whole system.
