Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in achieving efficient and omni-directional wireless communication due to radiation pattern blockage and interference from hinges, leading to suboptimal antenna performance and reduced maximum power levels.
Innovation Solution
The integration of a parasitic resonator in the cover and a resonator antenna in the hinge, coupled through a conductive gasket, minimizes radiation pattern blockage and interference by utilizing the hinge as an additional grounding mechanism, enhancing antenna performance and supporting a wide range of WiFi frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional antenna is used in the hinge area, then the antenna can be integrated into the information handling system, but radiation pattern blockage and interference occur leading to suboptimal antenna performance
Solution Approach 1:
The patent extracts the antenna from the hinge area where it would cause radiation pattern blockage. Instead, the antenna is positioned in the cover away from the hinge, eliminating the blockage problem while maintaining integration in the information handling system.
Solution Approach 2:
The patent introduces a parasitic resonator as an intermediary element between the antenna and the hinge. This parasitic resonator coupled through a conductive gasket serves to minimize radiation pattern blockage and interference from the hinge while allowing the antenna to maintain its positioning.
2Reliability
If the antenna is positioned away from the hinge to avoid interference, then radiation pattern blockage is minimized, but the antenna integration complexity increases
Solution Approach 1:
The parasitic resonator serves multiple functions: it acts as an intermediary to minimize radiation pattern blockage, provides coupling through the conductive gasket, and integrates with both the antenna and the hinge structure. This multi-functionality reduces overall system complexity despite the antenna being positioned away from the hinge.
3Power
If conventional antenna designs are used, then the design process is simple, but maximum power levels are reduced due to interference
Solution Approach 1:
The patent converts the potentially harmful interference from the hinge into a beneficial configuration by using the parasitic resonator coupled through a conductive gasket. This configuration minimizes radiation pattern blockage and allows the antenna to operate at higher maximum power levels while managing the hinge interference constructively.
