Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In miniaturized mobile devices, the conventional antenna design is hindered by electromagnetic interference from other electronic components and is often restricted in layout due to size constraints, leading to reduced performance and increased electromagnetic wave leakage.
Innovation Solution
The antenna pattern is arranged on a carrier with a first section set on the top surface of the touch module and a second section set on the side surface of the housing, forming a loop antenna that increases the distance from electronic components and reduces electromagnetic interference, allowing for improved antenna performance without obstructing the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna is disposed at the back cover of the device, then the antenna can be integrated into the housing, but the transmission of the antenna is influenced by the metallic back cover and electromagnetic interference from electronic components
Solution Approach 1:
The patent moves the antenna from the traditional back cover location to the side surface of the housing, utilizing a different spatial dimension. This repositioning allows the antenna to avoid interference from both the metallic back cover and internal electronic components while maintaining integration into the device structure.
Solution Approach 2:
The antenna is extracted from the back cover area and relocated to the side surface of the housing. This separation removes the antenna from the interfering electromagnetic environment created by the metallic back cover and electronic components, while the antenna remains integrated into the overall device structure.
2Volume of moving object
If the device size is miniaturized, then the device becomes more compact and portable, but the antenna layout is restricted and bandwidth is reduced
Solution Approach 1:
The patent utilizes the side surface of the housing as an additional dimensional space for antenna placement. This allows the antenna to achieve sufficient area for adequate bandwidth performance without increasing the device's footprint, effectively using vertical and lateral space rather than horizontal plane space.
Solution Approach 2:
The patent employs a flexible printed circuit board (FPC) as the carrier for the antenna pattern. This flexible substrate can be conformally arranged on the side surface of the housing, allowing the antenna to adapt to the available space while maintaining its electrical performance and bandwidth characteristics.
3Reliability
If shielding materials are added to reduce electromagnetic interference, then antenna performance is improved, but device complexity and size increase
Solution Approach 1:
The patent extracts the antenna from the interfering electromagnetic environment by relocating it to the side surface of the housing. This prevents interference from electronic components without requiring additional shielding materials, as the antenna is positioned outside the main interference zone while remaining integrated into the device.

AI summary
In a touch panel and display panel structure or an integrated touch display panel structure, an antenna pattern is disposed on a touch module, a display module or an integrated touch display module for an increased distance between the antenna pattern and electronic components below the structure, reducing electromagnetic effect caused by the electronic components and improving the antenna performance. The antenna pattern is arranged at two opposite edges of a top surface of the touch and display module or the integrated touch display module, and also at side surfaces of a housing non-coplanar to the top surface such that the antenna pattern is located outside the displaying area of the display module. Maintaining the effective antenna area and enhancing the working bandwidth of the antenna, the side width of surface of the touch panel and display panel structure or the integrated touch display panel structure is significantly reduced.
