Segmented Metal Frame Antenna Layout for 5G Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices supporting 5G frequency bands require specialized antennas formed by the laser-direct-structuring (LDS) process, which necessitates the presence of metal backplates or antenna base materials, limiting their application and flexibility.
Innovation Solution
An electronic device with a metal frame divided into three metal segments by gaps, where each segment functions as an antenna, enabling support for 5G and other communication networks without the need for antenna base materials, and allowing flexible antenna placement.

1Volume of moving object
If antennas are formed by the LDS process on outer shells, then efficient utilization of inner spaces is achieved, but antenna base materials (metal backplates or special plastic supports) must be disposed, limiting application flexibility
Solution Approach 1:
The metal frame is segmented into multiple independent metal segments separated by gaps, where each segment can function as an antenna element. This segmentation eliminates the need for a continuous metal backplate while maintaining antenna functionality, thereby resolving the contradiction between space utilization and application flexibility.
Solution Approach 2:
The metal frame segments serve dual purposes: they provide the structural framework of the electronic device and simultaneously function as antenna elements for wireless communication. This multi-functionality eliminates the need for separate antenna base materials, resolving the contradiction between efficient space use and application versatility.
2Reliability
If metal backplates are used for LDS antenna formation, then antenna support is provided, but the electronic devices without such base materials cannot meet LDS process requirements
Solution Approach 1:
Instead of requiring a continuous metal backplate, the invention uses segmented metal frame portions separated by gaps. Each segment provides localized antenna support and functions as an antenna element, maintaining reliability while enabling compatibility with devices that cannot accommodate full metal backplates.
Solution Approach 2:
The gaps between metal segments act as intermediaries that allow the antenna elements to be electrically isolated while maintaining structural integrity. This intermediary approach enables the LDS process to work on metal frames without requiring continuous backplates, resolving the contradiction between support stability and device compatibility.
