Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for multiple frequency bands, particularly with the advent of 5G technology, poses challenges in antenna layout due to limited clearance in full-screen and curved-screen devices, leading to reduced efficiency and increased costs.
Innovation Solution
The use of a metal frame with strategically placed gaps to divide it into independent frame segments, which function as antenna bodies supporting various frequency bands, including 5G, LTE, and other communication standards, thereby optimizing antenna layout and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If metal frame antennas are used to solve antenna layout problems, then antenna layout difficulty is reduced, but the number of antennas that can be made is limited requiring additional antennas
Solution Approach 1:
The metal frame is divided into multiple independent frame segments by setting gaps at specific positions. Each frame segment can independently support different frequency bands, allowing the same physical structure to function as multiple antennas without requiring additional components.
Solution Approach 2:
The frame segments are designed to support multiple frequency bands including 5G, LTE, and other communication standards. A single frame segment can support multiple frequency bands simultaneously, enabling one component to perform multiple antenna functions and reducing the total number of antennas needed.
2Adaptability or versatility
If more antennas are added to support multiple frequency bands, then communication standard support is improved, but cost increases
Solution Approach 1:
The frame segments are designed with multi-frequency band support capabilities, allowing a single segment to serve multiple communication standards (5G, LTE, etc.). This reduces the number of antenna components needed and lowers manufacturing costs while maintaining broad communication standard compatibility.
Solution Approach 2:
Multiple antenna functions are merged into the frame segments structure. By combining multiple frequency band support capabilities into single frame segments, the design reduces component count and manufacturing complexity while maintaining support for multiple communication standards.
3Adaptability or versatility
If more antennas are added in the device, then frequency band support is improved, but antenna performance is affected
Solution Approach 1:
By segmenting the metal frame into independent sections with gaps, each frame segment operates as an independent antenna element. This segmentation prevents interference between different frequency bands while maintaining optimal antenna performance for each band, unlike adding more antennas in the traditional sense.

AI summary
An electronic device and an antenna device are provided. The electronic device includes a metal frame defined with multiple gaps, and the multiple gaps divide the metal frame into multiple independent frame segments used as antenna bodies supporting frequency bands of communication standards. At least three frame segments of the multiple frame segments support a 5G frequency band, at least one frame segment of the at least three frame segments further supports an MHB frequency band of LTE, and at least one frame segment except the at least three frame segments of the multiple frame segments supports the MHB frequency band of LTE. At least one frame segment supporting the MHB frequency band of LTE except the at least three frame segments supporting the 5G frequency band is used for achieving a 5G NSA communication standard together with the at least three frame segments supporting the 5G frequency band.
