Distributed Antenna Structure for Smart Glasses RF Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices with multiple antenna structures within a single wearing member experience reduced antenna coverage and radio frequency signal loss due to the configuration of antenna structures within different wearing members connected via a single connecting member.
Innovation Solution
The electronic device incorporates a lens frame with a first and second wearing member, each containing an antenna structure, connected via a first and second connecting member, and a third connecting member within the lens frame, which enhances antenna coverage by allowing independent signal transmission and reduces radio frequency loss.

Engineering Contradiction Analysis
1Productivity
If multiple antenna structures are disposed within one wearing member, then data transmission speed and transmitted data capacity are increased, but antenna coverage is reduced
Solution Approach 1:
The patent divides the antenna system into multiple separate antenna structures disposed in different wearing members (first wearing member and second wearing member). Each antenna structure operates independently to provide coverage in different spatial directions, thereby maintaining comprehensive antenna coverage while enabling multiple data transmission channels for increased data transmission speed and capacity.
2Area of stationary object
If multiple antenna structures are disposed within different wearing member and connected via a single connecting member, then antenna coverage is maintained, but radio signal loss occurs
Solution Approach 1:
The connecting member is segmented into multiple separate connecting members (first connecting member and second connecting member). Each connecting member independently connects an antenna structure to the communication module, reducing signal loss by providing dedicated transmission paths. This segmentation prevents signal degradation that would occur with a single long connecting member spanning multiple wearing members.
Solution Approach 2:
The patent introduces a lens frame as an intermediary structure that houses the communication module and facilitates electrical connection between multiple connecting members and antenna structures. This intermediary arrangement optimizes signal transmission by providing a centralized connection point that minimizes the total length of connecting members and reduces the number of connection interfaces, thereby reducing radio signal loss.
3Area of stationary object
If multiple antenna structures are disposed within different wearing member, then antenna coverage is increased, but device complexity is increased
Solution Approach 1:
The wearing members and connecting members are designed to serve multiple functions: they provide structural support for the wearable device, enable mechanical connection between components, and simultaneously serve as mounting structures for antenna elements and signal transmission pathways. This multi-functionality reduces the need for additional dedicated components, thereby limiting the increase in device complexity despite the distributed antenna configuration.
