Transparent Pane Antenna with Variable Density for Vehicle Windshield Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles face challenges in integrating multiple antennas for communication systems without compromising vehicle design and styling, as the increasing number of antennas requires larger structures that can interfere with the vehicle's aesthetics and functionality.
Innovation Solution
A transparent pane assembly with an integrated antenna featuring two portions of different densities, where the denser portion is opaque and the less dense portion is more translucent, allowing for optimal light transmission and signal reception while maintaining a clear viewing area, and includes a trim component and a flexible layer for secure mounting and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are mounted on the vehicle roof to provide maximum reception capability, then signal reception quality is improved, but the size of housing structures increases and interferes with vehicle design and styling
Solution Approach 1:
The antenna is integrated directly into the transparent pane (windshield) structure, merging the antenna function with the existing vehicle component. This eliminates the need for separate roof-mounted housing structures while maintaining signal reception capability, as the transparent pane itself serves as the antenna substrate
Solution Approach 2:
The transparent pane serves dual functions: maintaining structural and visual integrity of the vehicle while simultaneously functioning as an antenna for signal reception. This multi-functionality reduces the need for additional dedicated antenna structures
2Reliability
If antenna density is increased to improve signal reception, then antenna performance is improved, but light transmission and viewing clarity deteriorate
Solution Approach 1:
The antenna structure implements varying conductor density across different regions of the transparent pane. Higher conductor density is placed in areas where signal reception is critical, while lower density is used in areas requiring better light transmission, creating localized optimization of both functions
Solution Approach 2:
The antenna design varies the physical parameters of the conductive elements, including density, trace width, and pattern configuration, across different portions of the transparent pane. This parameter variation allows optimization of both signal reception and light transmission in different areas
