Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to design an antenna module that can be customized for various mobile terminal models with limited installation space, particularly due to large displays on the front surface, requiring flexible and adaptable antenna configurations to meet different requirement specifications.
Innovation Solution
The antenna module includes a dielectric substrate with a circuit element mounting portion, an antenna element, and an exposed terminal portion, allowing for customizable antenna elements to be mounted on the exposed terminal portion, enabling flexible adaptation to different mobile terminal models by adjusting the positional relationship between the antenna elements on the substrate and those mounted on the terminal portion.

Engineering Contradiction Analysis
1Area of stationary object
If a patch antenna is used in a mobile terminal with a large display, then the display area is increased, but the available installation space for the antenna is reduced
Solution Approach 1:
The antenna system is segmented into a built-in antenna element on the dielectric substrate and an externally mountable antenna element on the exposed terminal portion. This segmentation allows the antenna function to be distributed, enabling flexibility in space utilization within the mobile terminal housing.
Solution Approach 2:
The patent utilizes the vertical dimension by providing antenna elements on both surfaces of the dielectric substrate. The circuit element mounting portion is on one surface while the exposed terminal portion for additional antenna elements is on the opposite surface, effectively using three-dimensional space to resolve the two-dimensional area constraint.
2Device complexity
If the antenna module installation place is limited, then the housing design is simplified, but the adaptability to different mobile terminal models is reduced
Solution Approach 1:
The dielectric substrate module serves multiple functions: it acts as both a circuit board for mounting the high-frequency integrated circuit element and as an antenna element itself, while also providing an exposed terminal portion for mounting additional antenna elements. This multi-functionality allows a single standardized module to adapt to various mobile terminal models.
Solution Approach 2:
The antenna system is made dynamically configurable by allowing different antenna elements to be mounted on the exposed terminal portion according to different mobile terminal model requirements. This enables the same base module to be adapted to various specifications without redesigning the entire antenna system.
