Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monopole antennas face challenges with manual soldering processes being time-consuming and expensive, leading to inconsistent solder joints, and significant electromagnetic wave energy loss in dielectric materials of printed circuit boards, particularly in high-frequency applications above 5 GHz, which reduces antenna efficiency and signal strength.
Innovation Solution
The monopole antenna assembly employs solderless connections using compression connections between the cable inner and outer conductors and a metal sheet ground plane, eliminating the need for manual soldering and reducing electromagnetic wave loss by replacing printed circuit boards with metal sheets, allowing for automated manufacturing and improved radiation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual soldering is used to connect cable conductors to the ground plane and radiator, then electrical connections can be made, but the process is time-consuming and expensive with inconsistent solder joint quality
Solution Approach 1:
The patent replaces the manual soldering process with a mechanical compression connection system. Conductive elements with compression connections are used to mechanically attach the cable inner conductor to the monopole radiator and the cable outer conductor to the ground plane, eliminating the need for soldering while providing consistent, reliable electrical connections that can be manufactured quickly and automatically.
2Loss of energy
If printed circuit boards are used as ground planes and signal carriers, then connections can be made, but electromagnetic wave energy loss is significant in high frequency applications above 5 GHz
Solution Approach 1:
The patent changes the fundamental material parameter of the ground plane from dielectric material (printed circuit board) to conductive metal material. The ground plane is now formed from a metal sheet rather than a printed circuit board, which significantly reduces electromagnetic wave energy loss in high frequency applications while maintaining ease of manufacture through standard metal forming and connection techniques.
