Touch Screen Antenna Integration for Design Freedom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna arrangements in mobile terminals restrict appearance and material design due to space constraints and interference from metal components, limiting aesthetic and practical design possibilities.
Innovation Solution
The antenna radiating body, signal line, and ground feeder line are integrated onto a touch screen's conducting layer, allowing for flexible placement in non-display areas and connection via FPC to RF and baseband chips, enabling better radiating performance without design limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If antenna is attached to shell as FPC or sheet steel and connected through leaf spring or PIN, then antenna can be formed as separate component, but it requires reserving enough area in shell structure and restricts appearance design
Solution Approach 1:
The patent merges the antenna radiating body directly onto the conducting layer of the touch screen, integrating the antenna function into the touch screen structure itself. This eliminates the need for separate antenna components attached to the shell, thereby removing design restrictions while maintaining manufacturing simplicity.
Solution Approach 2:
The conducting layer of the touch screen serves dual purposes: it functions as both the conductive element for touch detection and as the substrate for the antenna radiating body. This multi-functionality allows the same structure to support both touch screen operations and antenna radiation without requiring additional dedicated space.
2Reliability
If antenna needs to avoid metal component on shell for high radiation performance, then antenna radiation performance can be improved, but appearance design and material selection are restricted
Solution Approach 1:
The patent transitions the antenna from a three-dimensional separate component attached to the shell to a two-dimensional pattern directly formed on the conducting layer of the touch screen. This dimensional change allows the antenna to be integrated into the flat touch screen structure, eliminating interference from shell metal components while providing complete design freedom for appearance and materials.
3Ease of operation
If separate antenna structure is used with leaf spring or PIN connection, then antenna can be assembled independently, but terminal thickness increases and assembly complexity increases
Solution Approach 1:
The patent combines the antenna radiating body with the touch screen's conducting layer into a single integrated structure. This merger eliminates the need for separate antenna components, connection elements like leaf springs or PINs, and associated mounting structures, thereby reducing terminal thickness while maintaining assembly simplicity through the conducting layer's inherent flexibility.
