Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern electronic devices face space constraints and interference issues when integrating additional 5G antennas with existing 2G-4G antennas, necessitating innovative antenna solutions that support multiple radio access technologies (RATs) without increasing device size.
Innovation Solution
A MIMO antenna array with multiple antennas, including configurations that support 2G, 3G, 4G, and 5G RATs, is designed to occupy minimal space by leveraging existing hardware arrangements and minimizing interference, with specific antennas placed on the top and bottom portions of the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional 5G antennas are added to support 5G technologies, then 5G functionality is improved, but device space is consumed and placement is limited by existing 2G-4G antenna arrangements
Solution Approach 1:
The patent designs a multi-band antenna that can operate across multiple frequency ranges (700MHz-900MHz, 1700MHz-2100MHz, and 3GHz-5GHz) to support both legacy 2G-4G networks and 5G networks simultaneously. This single antenna structure replaces what would traditionally require multiple separate antennas, thereby maintaining 5G functionality while reducing the total area occupied in the device.
Solution Approach 2:
The patent combines multiple antenna functions into a unified antenna structure that integrates support for multiple radio access technologies (2G, 3G, 4G, and 5G) and multiple frequency bands. By merging these functions into one antenna element, the design eliminates the need for separate antenna placements and reduces the overall space required in the electronic device.
2Area of stationary object
If 5G antennas are placed close to existing 2G-4G antennas, then space is saved, but signal interference increases and performance deteriorates
Solution Approach 1:
The patent employs electromagnetic shielding structures and ground plane configurations that are locally optimized around the antenna elements. These local modifications create electromagnetic isolation zones that prevent interference between adjacent antenna elements while maintaining compact overall dimensions, thus achieving both space efficiency and signal quality.
3Reliability
If multiple separate antennas are used to support multiple RATs, then each RAT can be optimized, but device complexity and space requirements increase
