Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless equipment faces challenges in reducing radio frequency leakage from electronic components near antennas, affecting antenna efficiency, and in enhancing isolation between adjacent antennas due to spatial constraints.
Innovation Solution
The antenna module incorporates two antennas, a reflecting board with a shielding portion and open grooves, and extending plates that form a shielding cover. The open grooves enhance isolation between the antennas, while the extending plates and shielding portion serve as a shielding cover for electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shielding cover is added to block radio frequency leakage, then the antenna efficiency is improved, but the production cost increases
Solution Approach 1:
The patent merges the shielding cover function with the antenna module structure by integrating the reflecting board and extending plates directly into the antenna assembly. This combination eliminates the need for separate shielding components while maintaining the shielding effect, thereby reducing production cost without compromising antenna efficiency.
Solution Approach 2:
The reflecting board and extending plates serve multiple functions: they act as both the antenna radiating elements and the shielding cover simultaneously. This multi-functionality reduces the overall component count and production complexity while ensuring effective radio frequency shielding.
2Reliability
If the interval between two antennas is increased to improve isolation, then the interference between antennas is reduced, but the spatial constraints are violated
Solution Approach 1:
The patent applies local quality by creating a shielding zone specifically in the spacing area between the two antennas using the reflecting board and open grooves. This localized shielding approach improves antenna isolation without requiring increased overall antenna separation, thus maintaining compact device dimensions while reducing inter-antenna interference.
3Object-affected harmful factors
If a complete shielding cover is used to block radio frequency, then the shielding effect is improved, but the heat dissipation of electronic components is affected
Solution Approach 1:
The patent employs open grooves in the reflecting board that create a porous-like structure. This design allows radio frequency shielding while simultaneously permitting heat to escape from the electronic components. The open grooves act as thermal pathways that maintain heat dissipation efficiency while preserving the electromagnetic shielding effect.
