Reconfigurable Antenna Mounting Using a Secure Chassis Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in securely mounting antennas capable of transceiving Wi-Fi data at frequencies above 6 GHz without increasing chassis size or creating new input/output ports.
Innovation Solution
A reconfigurable antenna module design that utilizes a re-purposed SMA adapter port to securely mount various types of antennas, such as PIFA, LDS, or extendable puck antennas, to the rear wall of the chassis, using a reconfigurable antenna grounding bracket and security covers to ensure secure mounting and access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing mounting methods are used for antennas operating above 6 GHz, then antenna functionality is achieved, but chassis size must be increased or new I/O ports must be created
Solution Approach 1:
The existing SMA adapter port, originally designed for a different function, is repurposed to serve as a mounting interface for high-frequency antennas. This allows the same port structure to fulfill multiple functions: its original purpose plus antenna mounting and signal transmission, thereby enabling antenna adaptability without increasing chassis volume or creating new ports.
2Adaptability or versatility
If existing mounting methods are used for antennas operating above 6 GHz, then antenna functionality is achieved, but security and access control are compromised
Solution Approach 1:
The antenna mounting system is divided into separate functional components: the antenna element, the grounding bracket, and the security cover. The security cover acts as a distinct segment that provides access control and protection, while the grounding bracket ensures secure electrical and mechanical connection. This segmentation allows each component to specialize in its function, with the security cover specifically addressing the reliability concern.
3Reliability
If secure mounting structures are implemented, then mounting security is improved, but device complexity increases
Solution Approach 1:
The grounding bracket and security cover are combined into an integrated assembly that mounts through the existing SMA adapter port. The grounding bracket provides both electrical grounding and mechanical support, while the security cover integrates directly onto the bracket, creating a unified secure mounting structure. This merging reduces the number of separate components and simplifies the overall mounting process while maintaining security requirements.
