Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna modules fail to efficiently support multiple-band performance for wireless communication systems, as they often require antennas with different operating frequencies, which are not adequately addressed by a single dielectric layer due to varying electrical characteristics of electromagnetic waves.
Innovation Solution
The antenna module incorporates two antennas with different operating frequencies, each paired with a dielectric layer optimized for its specific frequency, allowing for separate focusing and resonance of electromagnetic waves, thereby enhancing multi-bandwidth radiation and gain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single dielectric layer is used for multiple-band antennas, then the device complexity is reduced, but the antenna performance deteriorates due to varying electrical characteristics at different frequencies
Solution Approach 1:
The patent divides the antenna system into separate first and second antennas, each optimized for specific frequency bands. The first antenna is configured for first frequency bands while the second antenna is configured for second frequency bands, allowing each antenna to be independently optimized for its designated frequency range, thereby resolving the performance degradation issue of using a single antenna for multiple bands
Solution Approach 2:
The patent applies different dielectric layers with different dielectric constants to different antennas. A first dielectric layer with a first dielectric constant is coupled to the first antenna, while a second dielectric layer with a second dielectric constant is coupled to the second antenna. This local optimization allows each antenna-dielectric combination to be tuned for its specific frequency bands, improving overall multi-band performance
2Adaptability or versatility
If multiple antennas with different operating frequencies are used, then multi-band performance is improved, but the device complexity increases
Solution Approach 1:
The patent creates an antenna module that simultaneously supports multiple frequency bands by integrating both first and second antennas with their respective dielectric layers into a single unified structure. This modular design allows the system to perform multiple functions (supporting different frequency bands) within a single integrated package, improving adaptability while managing complexity through systematic integration
