1Length of moving object
If the antenna module is configured in a limited space to meet thin and compact design requirements, then the device becomes thinner and more compact, but the signal transmission performance deteriorates due to space constraints
Solution Approach 1:
The patent utilizes the thickness direction (Z-axis) to arrange the electromagnetic shielding structure below the grounding plane, creating vertical separation between the antenna and noise sources. This three-dimensional spatial arrangement allows effective noise shielding while maintaining a compact overall thickness, resolving the contradiction between device thinness and signal transmission quality.
Solution Approach 2:
The grounding plane serves as an intermediary structure between the antenna and the electromagnetic shielding structure. It provides both electrical grounding for the antenna and a mounting surface for the shielding structure, enabling effective noise isolation while maintaining compact integration within the limited space.
2Ease of manufacture
If the electromagnetic shielding structure is integrated with the grounding plane, then the manufacturing cost and assembly complexity are reduced, but the shielding effectiveness may deteriorate due to potential integration issues
Solution Approach 1:
The electromagnetic shielding structure is integrally formed with the grounding plane as a single piece, eliminating the need for separate assembly steps. This merging of functions reduces manufacturing complexity and assembly operations while maintaining effective shielding performance through the integrated design that ensures proper electrical connection and spatial arrangement.
Solution Approach 2:
The grounding plane serves multiple functions simultaneously: it provides electrical grounding for the antenna, serves as a mounting base for the electromagnetic shielding structure, and acts as part of the overall shielding system. This multi-functionality reduces the number of separate components needed, simplifying manufacturing while maintaining shielding effectiveness.
