Cable-Integrated Radio Antenna for Small Receiver Signal Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniaturized terminals, such as smartphones and electronic keys, face challenges with antenna size limitations, leading to poor radio signal reception quality, fragility, and inability to optimize antenna orientation, which affects the restitution of audiovisual content.
Innovation Solution
Integrating the antenna into the power or communication cable, allowing it to be housed within the cable sheath, enabling better signal quality, flexibility, and protection, while avoiding interference with existing cable functions.

Engineering Contradiction Analysis
1Volume of moving object
If the antenna is made small to fit within miniaturized terminals, then the terminal size is reduced, but the reception quality deteriorates
Solution Approach 1:
The antenna is extracted from the terminal body and relocated to the cable. This allows the terminal to maintain its miniaturized form while the antenna, now outside the terminal constraints, can achieve sufficient size for good reception quality. The cable serves as the new support structure for the antenna.
Solution Approach 2:
The antenna is moved from the two-dimensional plane of the terminal's printed circuit board to the three-dimensional space provided by the cable. This dimensional transition allows the antenna to extend in multiple directions and achieve optimal length and orientation for signal reception without being constrained by the terminal's compact form factor.
2Device complexity
If the antenna is fixed on the terminal, then the terminal structure is simplified, but the antenna orientation cannot be optimized for reception
Solution Approach 1:
The antenna transitions from a fixed, static position on the terminal to a flexible, movable configuration within the cable. The user can adjust the antenna's orientation and position along the cable to optimize reception quality for different locations and signal sources, while the terminal itself maintains its simple, compact structure.
3Ease of operation
If the antenna is placed behind the television, then the terminal can be positioned conveniently, but the antenna sensitivity and effectiveness are reduced
Solution Approach 1:
The system is segmented into two independent components: the terminal and the antenna. The terminal can be positioned conveniently behind the television or in other optimal locations for data processing, while the antenna can be separately positioned in locations that maximize signal reception, such as near the television or in areas with better signal strength.
4Reliability
If the antenna is left hanging outside the receiver, then the antenna can be optimally oriented, but the device becomes difficult to handle and the antenna is fragile
Solution Approach 1:
The antenna is enclosed within the cable's protective sheath, which acts as a flexible protective shell. This protects the antenna from damage and makes the overall device more robust and easier to handle, while still allowing the antenna to be positioned and oriented optimally by adjusting its position within the flexible cable.

Function Achieved in This Case
This solution enhances antenna quality, reduces size constraints, and improves reception by allowing adjustable orientation and protection, while maintaining the cable's original functionality.
