Bezel Antenna Gap Layout With Reinforcement for Compact Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Antenna radiators formed by providing an antenna gap on the bezel of electronic devices suffer from reduced structural strength and antenna performance due to the compact and lightweight design of these devices, necessitating a solution that enhances structural strength while maintaining good antenna performance.
Innovation Solution
The integration of a reinforcement body between the display screen and the back cover, with conductive support legs positioned away from the display screen, enhances structural strength at the bezel's antenna gap area, allowing for improved antenna performance by increasing clearance and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an antenna gap is provided on the bezel to form antenna radiators, then antenna functionality is achieved, but structural strength at the bezel is reduced
Solution Approach 1:
The solution segments the structural support function from the antenna radiator components by introducing a separate reinforcement body. The reinforcement body is disposed opposite to the antenna gap and spaced from the radiators, creating distinct functional zones: the bezel with antenna gap for radiation functionality, and the reinforcement body for structural strength, thereby resolving the contradiction between antenna functionality and structural strength.
2Weight of moving object
If the electronic device is designed to be compact and lightweight, then portability is improved, but antenna performance is reduced due to limited space for radiator clearance
Solution Approach 1:
The invention utilizes the thickness direction (Z-axis) of the middle frame to resolve the spatial conflict. By positioning the reinforcement body in the thickness direction opposite to the antenna gap, and placing radiators on sides facing away from the display screen, the design creates adequate clearance for antenna performance in the lateral dimensions while maintaining compact overall device dimensions. This dimensional arrangement allows radiators to have sufficient clearance without increasing device footprint or weight.
3Volume of moving object
If radiators are positioned close to the display screen to save space, then device compactness is improved, but antenna performance deteriorates due to interference from the display screen
Solution Approach 1:
The invention employs asymmetric positioning of the radiators relative to the display screen. Instead of symmetric placement that would require maximum clearance from the display, the radiators are positioned on sides facing away from the display screen, creating an asymmetric layout that optimizes clearance from the interfering display while efficiently utilizing available space. This asymmetric arrangement minimizes interference from the display screen's metal components while maintaining compact device volume.

AI summary
Embodiments of this application provide an electronic device. Adjacent end portions of the first radiator and the second radiator are spaced apart to form an antenna gap. In a thickness direction of the middle frame, the display screen and the back cover are disposed on two opposite sides of the middle frame. The reinforcement body is located between the display screen and the back cover. Both the first conductive support leg and the second conductive support leg are spaced from the reinforcement body, and the reinforcement body is disposed opposite to the antenna gap. In the thickness direction of the middle frame, at least one of the first conductive support leg and the second conductive support leg is located on one side that is of the reinforcement body and that faces away from the display screen.
