Folded Antenna Assembly Layout for Easier Mobile Terminal Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to simplify the mounting process of antenna modules in mobile terminals while improving communication performance.
Innovation Solution
The proposed solution involves an antenna assembly with a substrate that includes a first sub-portion for the antenna units, a second sub-portion for the integrated circuit, and a bending portion connecting them. This design allows for easier integration and reduced interference between the antenna units and the integrated circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antenna modules are mounted inside the mobile terminal to improve communication performance, then wireless communication performance is improved, but the mounting process becomes more complex
Solution Approach 1:
The patent combines multiple antenna units and the integrated circuit onto a single substrate, creating an integrated antenna assembly. This merging approach maintains multiple antenna functions while simplifying the mounting process, as the entire assembly is installed as one unit rather than mounting separate antenna modules individually.
Solution Approach 2:
The substrate is divided into a first sub-portion for accommodating antenna units and a second sub-portion for accommodating the integrated circuit, connected by a bending portion. This segmentation allows optimized layout and electrical connection while maintaining overall integration, resolving the contradiction between functional complexity and mounting simplicity.
2Volume of moving object
If antenna units and integrated circuit are placed close together to reduce space, then device compactness is improved, but position interference between antenna units and integrated circuit increases
Solution Approach 1:
The substrate utilizes three-dimensional space by incorporating a bending portion that connects the first sub-portion (antenna units) and second sub-portion (integrated circuit) in a non-planar configuration. This dimensional approach allows compact overall size while maintaining adequate spatial separation between antenna units and the integrated circuit to minimize interference.
Solution Approach 2:
The substrate employs different regional configurations: the first sub-portion is optimized for antenna unit arrangement with appropriate spacing and grounding, while the second sub-portion is optimized for integrated circuit mounting. The bending portion provides transitional geometry that maintains signal integrity and reduces interference between these functionally distinct regions.
