Transparent Mesh Antenna Structure Balancing Light Transmission and Radiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional antennas are not transparent and when made so with a conductive layer, they compromise radiation efficiency, making it challenging to create a planar transparent antenna structure that balances transparency and efficiency.
Innovation Solution
A planar transparent antenna structure is designed with a mesh-like conductive layer, a parasitic patch conductive layer, and a radiation patch conductive layer in a ring structure, which are interlaced and connected to achieve high transmittance and radiation efficiency.

Engineering Contradiction Analysis
1Illumination intensity
If a transparent conductive layer is used to make the antenna, then transparency is improved, but radiation efficiency deteriorates
Solution Approach 1:
The conductive layer is segmented into a mesh-like structure composed of multiple wires interlaced and connected, rather than using a continuous transparent conductive layer. This segmentation reduces the total conductive material while maintaining electrical functionality and improving transparency.
Solution Approach 2:
Different regions of the antenna structure have different conductive layer configurations. The radiation patch conductive layer uses a mesh structure for transparency, while the ground conductive layer provides full coverage for reference. The parasitic patch conductive layer is selectively positioned to enhance radiation performance in specific areas.
2Loss of energy
If a continuous conductive layer is used for the antenna, then radiation efficiency is improved, but transparency deteriorates
Solution Approach 1:
The continuous conductive layer is divided into a mesh-like pattern of interlaced wires. This segmentation creates open spaces that allow light transmission while maintaining the electrical continuity needed for antenna operation through the interconnected wire structure.
Solution Approach 2:
The mesh-like conductive layer creates a porous structure with open spaces between the wires. This porous configuration allows light to pass through the antenna structure while the interconnected wires maintain the necessary electrical properties for effective radiation.
