Dual Antenna Wi-Fi Module Placement for Signal Degradation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wi-Fi signal degradation in computers due to the presence of a user's hands blocking the antenna, which can prevent wireless communication with other devices and the internet.
Innovation Solution
The placement of two Wi-Fi module antennas in separate regions of a computer or keyboard, such that a user's hands do not interfere with both antennas simultaneously, allowing for seamless data exchange by switching data transmission between the antennas based on signal degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single antenna is used in the computer, then the device complexity is reduced, but the Wi-Fi signal reliability deteriorates when user's hands block the antenna
Solution Approach 1:
The patent divides the single antenna function into multiple separate antennas positioned in different regions of the keyboard. This segmentation allows the system to maintain multiple independent signal paths, so when one antenna is blocked by the user's hands, another antenna can continue to transmit and receive Wi-Fi signals, thereby maintaining connectivity reliability.
2Ease of operation
If antennas are placed in regions that are easily accessible for user operation, then the ease of operation is improved, but the Wi-Fi signal quality deteriorates due to hand blocking
Solution Approach 1:
The patent distributes antennas across different spatial regions of the keyboard, utilizing the two-dimensional layout to create spatial separation. By placing antennas in different zones (e.g., top-left, bottom-right regions), the system ensures that the user's hands cannot simultaneously block all antenna positions, thus maintaining signal quality while preserving keyboard accessibility.
3Strength
If the computer housing is made with certain materials for structural integrity, then the strength is improved, but the Wi-Fi signal transmission deteriorates due to signal interference
Solution Approach 1:
The patent applies different material properties to different regions of the housing, particularly in the areas surrounding the antennas. By using signal-friendly materials (such as plastics or treated materials) in antenna regions while maintaining structural strength in other areas, the system reduces signal interference without compromising overall structural integrity.

AI summary
A system for reducing degradation of Wi-Fi signals for computers includes a first antenna of a Wi-Fi module disposed within a first region of the computer and a second antenna of the Wi-Fi module disposed within a second region of the computer wherein the regions are separated by a distance such that the first antenna and the second antenna are not subjected to degradation of the Wi-Fi signal at the same time due to a user's hands blocking the Wi-Fi signal when typing.
