Innovation Solution
The implementation of a housing structure with conductive first and second base portions, an antenna ground, a gasket, and a fixing member that electrically connects the antenna ground to the housing, ensuring stable high-frequency connections and maintaining antenna performance by using a gasket to connect the antenna ground to the top cover, thereby reducing manufacturing variations and deformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an antenna feeding member is fitted and fixed into a rear case member, then the antenna can be installed in the electronic apparatus, but manufacturing variations and deformations occur affecting antenna performance
Solution Approach 1:
The patent combines the antenna feeding member and rear case member into a single integrated housing structure with conductive base portions. This merging eliminates the fitting and fixing process between separate components, thereby preventing manufacturing variations and deformations that would otherwise occur at the interface between the antenna feeding member and rear case member.
Solution Approach 2:
The housing uses conductive materials for the base portions to ensure stable electrical connections for the antenna ground. The conductive housing structure provides both mechanical support and electrical functionality, reducing deformation and improving antenna performance stability through material selection.
2Reliability
If the antenna ground is connected to the housing using a gasket, then electrical connection is achieved, but connection stability may be compromised
Solution Approach 1:
The patent changes the electrical conductivity parameter of the housing base portions by using conductive materials. This allows the housing itself to provide stable electrical connection for the antenna ground, eliminating the need for additional gaskets while maintaining connection stability and rigidity.

AI summary
The housing includes a first base portion and a second base portion which are conductive respectively. The first base portion and the second base portion are disposed in contact. The antenna element is connected to the antenna ground. The antenna ground is formed on the antenna board. The gasket is located between the first base portion and the antenna ground in a height direction of the housing, and is conductive. The fixing member fixes the second base portion and the antenna ground so that the second base portion and the antenna ground are electrically connectable to each other in a state where the gasket is in contact with the first base portion and the antenna ground.
