Combo Antenna Module Non-Overlapping Radiation Pattern
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional combo antenna modules for mobile terminals suffer from degraded antenna performance for electronic payment due to the placement of a magnetic sheet over the entire substrate, which minimizes the radiation pattern area and affects the magnetic field strength and recognition range.
Innovation Solution
A combo antenna module design where the radiation pattern for electronic payment is strategically positioned to avoid overlapping with the magnetic sheet, allowing it to be partially exposed, thereby maintaining performance equivalent to larger designs while reducing mounting space and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the radiation pattern area for electronic payment is minimized to reduce mounting space, then mounting space is reduced, but antenna performance is degraded
Solution Approach 1:
The electronic payment radiation pattern is positioned specifically in the second area where the magnetic sheet is not disposed. This local positioning exploits the non-magnetic region to maintain optimal antenna performance despite the overall miniaturization of the device.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the magnetic field strength and recognition range for electronic payment by ensuring a portion of the radiation pattern does not overlap the magnetic sheet, maintaining performance despite reduced size and space constraints.
Implementation Method 1
a magnetic sheet disposed on a bottom surface of the base substrate, wherein a portion of the radiation pattern for electronic payment is disposed on an area where the base substrate and the magnetic sheet do not overlap
