Perpendicular Antenna Unit on Circuit Board for Frame Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to maintain excellent radiation performance of antenna devices in electronic devices while minimizing their size, particularly in devices with limited space, where the frame surrounding the display can interfere with the antenna, degrading its performance.
Innovation Solution
The antenna unit is positioned in a plane different from the surface of the circuit board at a predetermined angle, and multiple antenna units are arranged perpendicular to the circuit board to reduce interference with the frame, allowing for efficient radiation performance and miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the frame is provided around the display to mitigate damage, then the display is protected from impact, but the radiation performance of the antenna device is reduced
Solution Approach 1:
The patent positions the antenna unit in a plane different from the surface of the circuit board, specifically in a plane substantially perpendicular to it. This spatial reconfiguration moves the antenna away from the frame's interference zone while maintaining compact device dimensions, thus resolving the contradiction between display protection and radiation performance
2Reliability
If the antenna unit is placed in a plane different from the circuit board surface, then interference with the frame is reduced, but the device complexity increases
Solution Approach 1:
The patent integrates the antenna unit directly into the circuit board structure, where the circuit board serves as both the mounting substrate and part of the antenna's radiating structure. This merging approach maintains the perpendicular plane configuration for reduced interference while avoiding additional separate antenna components, thus controlling device complexity
