Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a 5G antenna device on conventional mobile terminals compatible with cellular or Wi-Fi systems poses a challenge due to space constraints, as it requires mounting all cellular, Wi-Fi, and 5G antenna devices, leading to increased terminal size.
Innovation Solution
The solution involves configuring the antenna device by using a module board with a 5G millimeter wave communication function to also operate as an antenna for lower frequencies, thereby sharing space and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate antenna devices for cellular, Wi-Fi, and 5G are mounted on the mobile terminal, then communication functionality is ensured, but the terminal size increases
Solution Approach 1:
The patent applies multi-functionality by enabling the module board to serve dual purposes: it functions as both a 5G millimeter wave antenna and a cellular/Wi-Fi antenna for lower frequencies. This is achieved by configuring the module board with 5G functionality to operate across multiple frequency bands, thereby eliminating the need for separate antenna devices and reducing overall terminal size while maintaining full communication functionality
Solution Approach 2:
The patent merges the functions of multiple antenna devices into a single integrated module board. By combining the 5G antenna function with cellular and Wi-Fi antenna capabilities on the same board, the design reduces the number of separate components needed, optimizes space utilization, and decreases the terminal's overall volume
