Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization and multi-functionality of electronic devices limit the number of antenna modules that can be mounted, making it challenging to achieve optimized coverage for high-frequency wireless signals, particularly for 5G communication, while also supporting legacy mobile communication.
Innovation Solution
The electronic device incorporates multiple antenna modules, including patch and dipole antenna elements strategically placed around the device to ensure omnidirectional coverage without interfering with each other, using the side bezel structure as a radiator for legacy signals and integrating patch antenna elements to face the back plate for enhanced high-frequency signal transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antenna modules are mounted to achieve omnidirectional coverage for high-frequency signals, then wireless communication coverage is improved, but device complexity increases
Solution Approach 1:
The side bezel structure is designed to serve dual purposes: it acts as a structural component of the device housing and simultaneously functions as a radiator for legacy mobile communication signals. This multi-functionality reduces the need for separate dedicated radiator components, thereby lowering device complexity while maintaining communication coverage.
Solution Approach 2:
Antenna elements are arranged in three-dimensional space around the device, with patch antenna elements positioned on different surfaces (front plate, back plate, side bezel) to achieve omnidirectional coverage. This spatial distribution in multiple dimensions enables comprehensive signal coverage without requiring an excessive number of antenna modules in any single plane.
2Ease of manufacture
If antenna modules are densely packed to save mounting space, then ease of manufacture is improved, but interference between antenna modules increases
Solution Approach 1:
Different regions of the device are assigned different antenna elements based on their local characteristics and requirements. Patch antenna elements are strategically positioned on the front plate, back plate, and side bezel to create localized radiation zones. This spatial separation of antenna functions reduces mutual interference while maintaining efficient use of the limited mounting space within each regional zone.
3Measurement precision
If patch antenna elements are positioned to face the back plate for high-frequency signal transmission, then signal transmission quality is improved, but device complexity increases
Solution Approach 1:
The side bezel structure is integrated with the antenna system, serving both as a structural support component and as a mounting platform for patch antenna elements. This merging of structural and functional components eliminates the need for separate antenna support structures, thereby reducing device complexity while maintaining the optimized positioning of antenna elements for high-frequency signal transmission.
