Metal Border Antenna Layout to Reduce Hand Blocking Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of a metal border in electronic devices can block antenna structures, affecting their performance, particularly when the device is held by a user.
Innovation Solution
An electronic device design featuring a metal border with an inward-extending antenna connection part and a support frame with an avoidance notch, allowing the antenna connection part to penetrate or be accommodated within the notch, maintaining a specific interval with the support frame to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the metal border is used as part of the antenna structure, then the structural strength is improved, but the antenna performance deteriorates due to hand blocking interference
Solution Approach 1:
The metal border is divided into multiple sections: a first border section that forms part of the antenna structure and a second border section that provides structural support. This segmentation allows the antenna-forming portion to be positioned away from the user's hand while maintaining overall structural integrity through the remaining border sections.
Solution Approach 2:
The antenna connection part extends inward from the first border section toward the display, positioning the antenna structure in a different spatial dimension (depth/thickness direction) rather than solely along the border perimeter. This dimensional change allows the antenna to be located in a region less affected by hand blocking during device usage.
2Reliability
If the antenna connection part is positioned on the inner side of the first border section, then the antenna performance is improved by reducing hand blocking, but the device complexity increases due to additional structural components
Solution Approach 1:
The antenna connection part is integrated with the first border section to form a unified structure. The first border section serves dual functions: providing structural support as part of the device frame and forming part of the antenna structure. This merging reduces the need for separate antenna components while achieving improved antenna performance.
Solution Approach 2:
The first border section is designed to perform multiple functions simultaneously: it provides mechanical support as part of the device frame, serves as an antenna element for signal transmission, and houses the antenna connection part. This multi-functionality reduces overall device complexity by eliminating the need for dedicated antenna components.
