Antenna Relocation to Motor PCB for Stabilizer Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The performance of antennas in electronic devices with stabilizer functions is degraded due to user grip and metal parts, which interfere with communication signals.
Innovation Solution
The antenna is positioned in a non-grip area of the device, such as the connection portion, and integrated into a motor PCB, allowing the processor to control the support member and communication circuit to transmit signals via the antenna radiator, reducing interference from metal parts and user grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the antenna is mounted on the main PCB inside the handle, then the device structure is compact, but the antenna performance is degraded due to user grip and metal parts
Solution Approach 1:
The antenna is extracted from the main PCB inside the handle and relocated to a separate motor PCB positioned in the connection portion between the handle and support member. This extraction removes the antenna from the grip area, eliminating signal degradation caused by user hand contact and metal parts in the handle.
Solution Approach 2:
The motor PCB serves as an intermediary carrier for the antenna, positioned in the connection portion that acts as a transition zone between the handle and support member. This intermediary location provides electromagnetic isolation from both the metal housing and user grip areas while maintaining structural integration.
2Strength
If metal parts are used for housing and support members to ensure strength, then structural strength is improved, but antenna signal is interfered with
Solution Approach 1:
The antenna is extracted from proximity to metal parts by relocating it to the motor PCB in the connection portion. This spatial separation minimizes electromagnetic interference from the metal housing and support members while preserving their structural function.
Solution Approach 2:
The connection portion where the motor PCB with antenna is located serves as a localized non-conductive zone between the metal handle and metal support member. This creates an electromagnetic isolation corridor that allows metal parts to maintain structural strength without degrading antenna performance.
