Antenna Mounting on Notched Supporting Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook and tablet computers face space constraints at the top of the screen, leading to noise interference between the antenna and image-capturing unit, and have complex assembly processes due to a copper foil ground layer, increasing costs.
Innovation Solution
The antenna is positioned on a supporting frame with a notch on the lateral side of the housing, utilizing the frame as a ground element instead of a copper foil layer, which simplifies assembly and reduces noise by preserving space at the top for other electronic elements.

1Area of stationary object
If the antenna is disposed at the top side of the screen adjacent to the image-capturing unit, then the antenna can be mounted in limited space, but noise occurs and transmission performance is deteriorated
Solution Approach 1:
The antenna is relocated from the top side of the screen to the lateral side of the housing, utilizing a different spatial dimension. This dimensional change allows the antenna to be positioned in the notched supporting frame on the side, away from the image-capturing unit, thereby reducing noise interference while still utilizing limited mounting space effectively.
2Reliability
If a copper foil ground layer is disposed between the housing and the display, then the antenna can be coupled to a ground element, but the assembly process becomes complicated and cost increases
Solution Approach 1:
The supporting frame is designed to serve dual functions: mechanically supporting the display and providing an electrical ground connection for the antenna. By merging these two functions into a single component, the need for a separate copper foil ground layer is eliminated, simplifying the assembly process and reducing costs while maintaining reliable ground connection.
Solution Approach 2:
The supporting frame is transformed from a single-function mechanical support structure into a multi-functional component that simultaneously provides mechanical support and electrical grounding. This universal design allows the same component to fulfill multiple roles, reducing the total number of parts and assembly steps.
