Mobile Terminal Antenna Switching for Camera Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The radiation performance of antennas in mobile terminals is deteriorated due to the unfavorable antenna environment caused by the placement of cameras, leading to suboptimal network service quality.
Innovation Solution
A controllable switch is introduced between the antenna and the network path, allowing the mobile terminal to switch between different network paths and antennas, ensuring that the network service is provided via the antenna with higher radiation performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera is located in proximity to the WiFi antenna at the top of the mobile terminal, then the camera can be arranged at a convenient position, but the radiation performance of the WiFi antenna is deteriorated
Solution Approach 1:
The patent introduces a controllable switch as an intermediary component between the network path and antennas. This switch enables dynamic selection of different antenna connection states, allowing the system to bypass the deteriorated WiFi antenna and connect through the 4G diversity antenna instead, thus resolving the conflict between camera placement convenience and antenna performance
Solution Approach 2:
The patent implements dynamic antenna selection by making the antenna connection state controllable rather than fixed. The controllable switch allows the system to adaptively change the network path connection based on which antenna provides better radiation performance, transforming a static antenna arrangement into a dynamic, selectable system
2Area of stationary object
If the WiFi antenna and 4G diversity antenna are both located at the top of the mobile terminal, then the antenna layout is compact, but the antenna environment is affected and radiation performance is reduced
Solution Approach 1:
The patent applies dynamic selection to resolve the compactness versus performance contradiction. By maintaining both antennas in a compact top-location arrangement but enabling dynamic switching between them through the controllable switch, the system achieves both compact layout and optimal radiation performance
