Foldable WiGig Antenna Structure for Stable Headset Directivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
WiGig technology at 60 GHz suffers from poor penetrability and short transmission distance due to signal blocking by objects, and antennas face challenges with directivity, leading to incomplete or incorrect data reception during user movements.
Innovation Solution
An antenna structure capable of transmitting WiGig bands, which can be folded or extended to adjust its position and maintain directivity, ensuring stable data transmission. The antenna structure includes two body portions with pivoting and signal transceiving ends, allowing for adjustments in the left-right, front-back, and upward directions to optimize signal reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If WiGig technology is used for wireless transmission at 60 GHz, then data transmission speed is improved (up to 7 Gbit/s), but signal penetrability deteriorates due to blocking by objects such as walls, ceilings and floors
Solution Approach 1:
The patent applies the dynamics principle by making the antenna structure movable and adjustable. The antenna can be folded and extended, and its position can be dynamically adjusted to different locations (left side, right side, front, back, upward direction) to maintain optimal signal reception despite user movements and changing environmental conditions, thereby compensating for the poor penetrability of WiGig signals.
2Device complexity
If a fixed antenna position is used, then device structure is simplified, but directivity deteriorates during user movements such as shaking, turning back, or bowing
Solution Approach 1:
The antenna structure is designed with dynamic adjustment capability, allowing it to be folded and extended. The antenna can be positioned at multiple locations relative to the base (left side, right side, front, back, upward direction), enabling it to maintain proper directivity during user movements while keeping the base structure relatively simple.
Solution Approach 2:
The antenna system is segmented into a base and a movable antenna portion. This segmentation allows the antenna to be independently positioned and adjusted relative to the base, providing flexibility in maintaining directivity without requiring the entire device structure to be complex.
3Reliability
If antenna is extended to increase valid range for wireless signal, then directivity is improved, but ease of storage and carrying deteriorates
Solution Approach 1:
The antenna structure employs dynamic folding and extending mechanisms that allow it to be compact when not in use and extended when needed. This enables the antenna to provide a large valid range for wireless signal transceiving during operation while maintaining ease of storage and carrying when folded.
Solution Approach 2:
The antenna structure can be folded back onto itself or nested within the base device, similar to a nested doll configuration. This allows the extended antenna structure to be compacted into a small form factor for convenient storage and carrying, while still providing full extension capability when needed for optimal signal reception.
