Terminal Device Composite Radiator Design for 5G Signal Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In terminal devices, such as mobile phones, the limited space and high screen ratio lead to degraded antenna performance due to the constraints on available space for antennas, especially with the introduction of 5G technology which requires more antennas for high-speed communication.
Innovation Solution
A conducting layer is disposed on the inner surface of the back shell of the terminal device's housing, coupled with a first radiator to form a second radiator, enhancing the receiving and transmitting of wireless signals by increasing power and radiation area, while minimizing space occupancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the number of antennas is increased to achieve 5G high-speed communication, then communication speed is improved, but the available space for antennas is exceeded and antenna performance is degraded
Solution Approach 1:
The patent combines the first radiator and the conducting layer to form a composite radiator structure. The conducting layer on the back shell is coupled with the first radiator to form a second radiator, creating a merged antenna system that improves communication performance within limited space
Solution Approach 2:
The patent utilizes the back shell surface as a two-dimensional plane for placing the conducting layer, transforming the traditional three-dimensional volume-based antenna design into a surface-based configuration. This allows effective use of the back shell area to enhance antenna performance without increasing device volume
2Volume of moving object
If the space occupancy is minimized to accommodate more components, then device compactness is improved, but antenna performance is degraded due to insufficient radiation area
Solution Approach 1:
The patent compensates for limited three-dimensional space by utilizing the two-dimensional surface area of the back shell. The conducting layer is disposed on the back shell surface to provide sufficient radiation area while maintaining compact device volume
Solution Approach 2:
The patent merges the first radiator with the conducting layer on the back shell to form a composite radiator system. This combination creates an effective large radiation area without requiring proportionally large physical space, as the conducting layer utilizes the back shell surface area
