Antenna Structure with Segmented Metal Frame for 5G Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of 5G antennas into wireless communication devices poses a challenge as it overcrowds the existing antenna space, potentially affecting the performance of other antennas and reducing design flexibility, especially given the higher frequency bands required for 5G communication.
Innovation Solution
The antenna structure incorporates a metal frame with strategically placed gaps and slots filled with insulating materials, allowing for the coexistence of multiple antennas, including 5G sub-6 GHz antennas, by separating radiating portions and using multiple feed sources to maintain performance across various frequency bands.

Engineering Contradiction Analysis
1Quantity of substance
If 5G antennas are added to the existing antenna space, then the transmission bandwidth is improved, but the performance of other antennas is affected and design flexibility is reduced
Solution Approach 1:
The metal frame is divided into multiple segments by setting gaps at specific positions, creating independent antenna regions. Each segment can support different antenna functions (4G, GPS, WLAN, 5G) without interfering with each other, allowing 5G antennas to be added while maintaining performance of other antennas.
Solution Approach 2:
The patent utilizes the vertical dimension by setting gaps at different heights (first gap at first height, second gap at second height) to create three-dimensional antenna spacing. This vertical separation allows multiple antenna types to coexist in the limited device space while preventing performance degradation through proper spatial isolation.
2Quantity of substance
If 5G antennas are added to the existing antenna space, then the transmission bandwidth is improved, but the design flexibility is reduced
Solution Approach 1:
The metal frame structure with strategically placed gaps serves multiple functions simultaneously: it provides mechanical support, creates antenna segmentation, enables electromagnetic isolation, and allows flexible antenna configuration. This universal structure can accommodate different antenna types and configurations without requiring complete redesign.
Solution Approach 2:
The antenna design employs adjustable and configurable elements such as variable gap positions and sizes, allowing the antenna system to be dynamically optimized for different frequency bands and antenna configurations. This dynamic flexibility enables the same basic structure to adapt to 4G, 5G, GPS, and WLAN requirements.

AI summary
An antenna structure includes a metal frame, at least one feed source, and a feed portion. The metal frame includes at least one radiating portion and at least one slot. The at least one slot is disposed in the at least one radiating portion or adjacent to the at least one radiating portion. The at least one feed source and the at least one radiating portion form a first antenna. The feed portion and the at least one slot form a second antenna. The at least one feed source supplies an electric current for the first antenna, thereby exciting a first working mode and generating a radiation signal in a first frequency band. The feed portion spans the at least one slot to supply the electric current for the second antenna, thereby exciting a second working mode and generating a radiation signal in a second frequency band.
