Solution Overview

Problem

As electronic devices with expanded displays occupy most of the front surface, it becomes challenging to secure the middle band antenna performance due to reduced antenna area, leading to performance deterioration and interference issues with the display and lower end metal housing.

Innovation Solution

Incorporating a conductive portion on the side member of the electronic device's housing, which includes a curved edge portion and a conductive pattern along the inner surface, to operate as an antenna, ensuring electrical length for target frequency signals and mitigating communication performance degradation.

VSEngineering Contradiction Analysis

1Adaptability or versatility

If antennas are arranged on the left and right side surfaces, then additional antenna functions are provided, but interference occurs with the lower end metal housing antenna and display ground area

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by creating a curved edge portion at a specific location on the side member where the antenna will be positioned. This localized curvature distinguishes the antenna region from other parts of the housing, allowing the conductive pattern to be selectively formed only in this area. The curved edge portion serves as a dedicated antenna zone that is spatially separated from the lower end metal housing antenna and display ground area, thereby reducing interference while maintaining additional antenna functionality.
