Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of 5G antennas into wireless communication devices poses a challenge as it crowds the existing antenna space, potentially affecting the performance of other antennas and reducing design flexibility, especially given the higher frequency bands required by 5G communication.
Innovation Solution
The antenna structure incorporates a metal frame with substrates that include gaps and feed portions, allowing for adjustable resonance frequencies through switches, enabling the coexistence of multiple antennas such as 4G, GPS, WLAN, and 5G antennas without compromising performance, by using flexible printed circuit boards and strategically placed slots in the metal frame to optimize antenna placement and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If 5G antennas are added to the existing antenna space, then the transmission bandwidth is increased, but the performance of other antennas is affected and design flexibility is reduced
Solution Approach 1:
The metal frame is divided into multiple segments with gaps between them, allowing different antenna elements to be positioned at specific locations. This segmentation enables the integration of multiple antenna functions (4G, GPS, WLAN, 5G) without interference, as each antenna can be independently positioned and optimized in its designated segment.
Solution Approach 2:
The patent utilizes the vertical dimension by positioning antennas at different heights and depths within the device housing. The metal frame segments are arranged at various vertical levels, allowing 5G antennas to be added without occupying the same spatial plane as existing antennas, thereby avoiding performance degradation while increasing overall transmission bandwidth.
