Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antennas in compact mobile devices struggle to meet the expanded bandwidth requirements of 4G mobile communication due to limited space and the need for additional antennas and coaxial cables, with existing methods only providing limited bandwidth improvements.
Innovation Solution
An antenna module with a first conductive unit, a second conductive unit, and a third conductive unit, where the second and third units are electrically connected and generate opposite currents through induction, allowing for multiple resonance modes with a single feeding point, reducing the need for additional coaxial cables and space, and integrating with an insulation body to minimize size and manufacturing cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If another antenna of different operation band is configured to broaden bandwidth, then the available bandwidth is increased, but the device dimension is significantly increased
Solution Approach 1:
The patent combines multiple conductive units (first, second, and third conductive units) into a single integrated antenna structure that supports multiple operation bands. The conductive units are electrically connected through specific configurations, allowing one antenna to perform the function of multiple antennas, thereby broadening bandwidth without increasing device dimension.
Solution Approach 2:
The antenna structure is designed to serve multiple functions by supporting different operation bands (e.g., 700 MHz and 960 MHz) within a single antenna module. The conductive units can be configured to resonate at different frequencies, enabling the antenna to handle multiple communication standards and bands simultaneously.
2Adaptability or versatility
If capacitance or inductance matching circuit is configured to broaden bandwidth, then the bandwidth is slightly improved, but the improvement is insufficient for 4G requirements
Solution Approach 1:
The patent achieves bandwidth broadening by changing the physical and electrical parameters of the conductive units themselves, such as their dimensions, positions, and electrical connections, rather than relying on external matching circuits. By adjusting the resonance characteristics of the conductive units, the antenna can cover wider frequency ranges including 4G requirements.

The antenna module achieves a broader bandwidth range within the limited space of compact devices, satisfying 4G mobile communication specifications without increasing device size, reducing complexity and manufacturing costs, and enabling multiple operation bands.
Implementation Method 1
the second conductive unit generates a second current. Herein the current directions of the first current and the second current are opposite. In one embodiment, the second current is an induced current.
Implementation Method 2
the first conductive unit generates a first band by a resonance of the first current, and the second conductive unit generates a second band by a resonance of the second current.
