Antenna Structure in Pivot Assembly for Transformable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transformable notebook computers face challenges in maintaining stable signal transmission due to the metal casing shielding the antenna as the screen changes positions, affecting wireless communication performance.
Innovation Solution
The antenna structure is integrated into the pivot assembly, allowing it to remain unchanged relative to the metal casing during position adjustments, utilizing a slot antenna and monopole antenna configuration that are not coplanar to prevent interference and enhance frequency coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the antenna is disposed within the screen of the transformable notebook computer, then the device can be compact and integrated, but the metal casing shields the antenna and degrades signal transceiving ability when the screen changes positions
Solution Approach 1:
The patent positions the antenna in the pivot assembly rather than within the screen body, changing the spatial dimension of antenna placement. This allows the antenna to be located in a region that does not experience shielding from the metal casing during screen actuation, thereby maintaining signal transceiving ability while achieving compact integration.
Solution Approach 2:
The antenna is extracted from the screen body and placed in the pivot assembly. This separation removes the antenna from the shielding environment of the metal casing, allowing it to maintain stable signal transmission while the screen can freely change positions relative to the host.
2Device complexity
If a single antenna is used in the pivot assembly, then the structure is simple, but the frequency coverage is limited
Solution Approach 1:
The patent combines two different antenna types (slot antenna and monopole antenna) into a single integrated antenna structure in the pivot assembly. The slot antenna provides coverage for one frequency band while the monopole antenna covers another, achieving broad frequency coverage without requiring separate antenna systems.
Solution Approach 2:
The integrated antenna structure in the pivot assembly serves multiple functions by incorporating both slot and monopole antenna elements. This single structure can transmit and receive signals across multiple frequency bands, making the wireless communication system versatile without increasing overall device complexity.

AI summary
An electronic device having antenna structure is provided. The electronic device includes a first body, a pivot assembly, a second body and an antenna structure. The pivot assembly is pivoted to the first body along a first axis. The second body is pivoted to the pivot assembly along a second axis. The antenna structure is disposed in the pivot assembly and has a first radiation portion, a second radiation portion and a third radiation portion. The first radiation portion and the second radiation portion have a slot therebetween to form a slot antenna. The third radiation portion forms a monopole antenna and is aligned to the slot. The third radiation portion and the slot are not coplanar.
