Display-Integrated Antenna Layout for Metal Unibody Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal devices face challenges with complex antenna structures, high product costs, and poor consistency due to the stacking contradiction between metal unibody and antennas, which complicates assembly and increases the width of the black edge, limiting layout freedom and increasing assembly difficulty.
Innovation Solution
A terminal device design featuring an antenna component with a radiating metal sheet that includes a first radiating part extending parallel to the display component and a second radiating part extending away from it, connected to the circumferential edge, along with a feeding point and grounding structure, allowing for a dual patch and cavity antenna configuration that enhances radiation performance and frequency coverage while simplifying production and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional antenna structures are used in metal unibody devices, then antenna function is achieved, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines the antenna component with the display component by integrating the radiating element into the display assembly. The radiating element is positioned between the front and rear displays, utilizing the display component's structure as part of the antenna system, thereby reducing overall device complexity while maintaining antenna functionality
Solution Approach 2:
The display component serves dual functions: as the user interface display and as part of the antenna system. The radiating element integrated into the display assembly allows the display component to function both as a visual interface and as an antenna structure, reducing the need for separate dedicated antenna components
2Reliability
If complex antenna structures are used, then radiation performance is improved, but product cost increases
Solution Approach 1:
By merging the antenna function with the display component, the patent eliminates the need for separate antenna assemblies and their associated mounting, grounding, and feeding structures. This integration reduces part count and assembly steps, directly lowering manufacturing costs while maintaining radiation performance through the dual patch and cavity configuration
Solution Approach 2:
The patent achieves improved radiation performance through parameter optimization of the radiating element, including its geometry, positioning, and electrical characteristics, rather than through structural complexity. The dual patch and cavity design allows for tuned resonant frequencies and improved impedance matching, achieving better performance through parameter control rather than added complexity
3Reliability
If antenna components occupy black edge area, then antenna function is achieved, but screen ratio decreases
Solution Approach 1:
The patent moves the antenna function from the lateral black edge area into the vertical space between the front and rear displays. By utilizing the Z-dimension (thickness direction) rather than the X-Y plane, the radiating element achieves antenna functionality without occupying the black edge area, thereby preserving screen ratio while maintaining antenna performance
4Reliability
If multiple antenna components are stacked, then frequency coverage is improved, but assembly complexity increases
Solution Approach 1:
The patent merges multiple radiating elements and their associated grounding and feeding structures into a single integrated display component assembly. The dual patch and cavity configuration provides wide frequency coverage, while the integration into the display assembly eliminates the need for separate stacking and assembly of multiple independent antenna components, reducing assembly complexity
