Movable Antenna Module Layout for SIM Card Slot Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The compact design of 5G mobile terminals faces challenges in accommodating millimeter wave and Sub 6 GHz antennas due to the limited space, often requiring users to manually remove these antennas to access SIM cards, which is not a typical user behavior and can complicate antenna layout.
Innovation Solution
A mobile terminal assembly with a first antenna module that can be switched between two positions, allowing it to be placed between the SIM card holder and the SIM card slot, enabling the antenna to be moved out of the way when a SIM card is inserted or removed, thus optimizing internal space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 5G mobile terminal assemblies adopt millimeter wave antennas or Sub 6 GHz MIMO antennas, then 5G signal reception capability is improved, but antenna space inside the device becomes insufficient
Solution Approach 1:
The antenna module is designed to be movable between a first position (inside the device housing) and a second position (outside the device housing). This dynamic positioning allows the antenna to occupy internal space during normal operation and be moved externally when SIM card access is required, resolving the space conflict between 5G antenna requirements and SIM card slot accessibility
Solution Approach 2:
The patent utilizes the third dimension (depth/extension outside housing) to resolve the two-dimensional space conflict within the device. By allowing the antenna module to extend outside the housing when needed, the design creates additional spatial freedom without increasing the device's footprint, enabling both 5G antenna functionality and SIM card access
2Volume of moving object
If the antenna module is placed inside the device housing, then device compactness is improved, but SIM card access becomes difficult
Solution Approach 1:
The antenna module transitions from a static internal position to a dynamic position that can extend outside the housing. This allows the antenna to be compact within the device during normal use while being movable to an external position when SIM card operations are needed, maintaining both compactness and operational ease
Solution Approach 2:
The antenna module is designed as a separate, independently movable component that can be positioned differently from other device components. This segmentation allows the antenna to be relocated without affecting the SIM card holder or other internal structures, enabling flexible space management

AI summary
A mobile terminal assembly and a mobile terminal are disclosed. The mobile terminal assembly may include a housing, a card holder assembly and a first antenna module. The housing is provided with a card slot; the card holder assembly is located at the card slot and is configured to carry a memory; and the first antenna module is installed in the housing. The first antenna module is configured to be switched between a first position and a second position under the action of an external force. When the first antenna module is located at the first position, the card holder assembly is located in the housing, and the first antenna module is located between the card holder assembly and the card slot; and when the first antenna module is located at the second position, the holder assembly at least partially passes through the card slot to extend outside the housing.
