Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of 5G communication frequency bands into existing wireless communication devices poses a challenge as it overcrowds the original antenna space, potentially affecting the performance and flexibility of the antenna design, especially when using metal frames with gaps for different functions like 4G GPS and WLAN.
Innovation Solution
The antenna structure incorporates a metal frame with multiple antennas, each featuring a T-shaped cross-section gap configuration and a feed portion that excites distinct resonance modes for different frequency bands, allowing for efficient use of space and maintaining performance by accommodating 5G sub-6 GHz frequencies without compromising existing antenna functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If 5G antennas are added to the original antenna space, then the transmission bandwidth is improved, but the performance of the original antenna is affected and the flexibility of antenna design is reduced
Solution Approach 1:
The metal frame is divided into multiple segments by setting gaps at specific positions, creating independent antenna regions. Each gap segment can be independently configured for different frequency bands (4G, GPS, WLAN, 5G), allowing multiple antennas to coexist without mutual interference while maintaining individual performance characteristics
Solution Approach 2:
Different regions of the metal frame are assigned different electromagnetic properties through strategic gap placement. Specific gaps are optimized for specific functions (e.g., certain gaps for 5G sub-6GHz, others for GPS or WLAN), enabling each region to perform its designated function optimally without affecting other regions
2Quantity of substance
If 5G antennas are added to the original antenna space, then the transmission bandwidth is improved, but the flexibility of antenna design is reduced
Solution Approach 1:
The metal frame structure serves multiple functions simultaneously: it provides the device structural framework, acts as a ground plane, and functions as an antenna element. The gap configuration enables the same structure to support multiple frequency bands and antenna types (4G, GPS, WLAN, 5G), eliminating the need for separate antenna structures and maintaining design flexibility
Solution Approach 2:
The antenna design allows for dynamic configuration of gap dimensions and positions to optimize performance for different frequency bands. The same metal frame structure can be adapted for different 5G bands (sub-6GHz and毫米波) by adjusting gap parameters, providing ongoing design flexibility even as new frequency requirements emerge

AI summary
An antenna structure includes a metal frame. The metal frame includes a first surface, a second surface, and a third surface. The third surface is located between the first surface and the second surface. The metal frame includes at least one antenna. The at least one antenna includes a first gap, a second gap, and a feed portion. The first gap is disposed between the first surface and the second surface. The second gap is disposed in the third surface. The feed portion is mounted on the first surface and spans the first gap. When the feed portion supplies an electric current, the electric current is coupled to the first gap and the second gap.
