Antenna Array Switching to Cut RF Front-End Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna structures in electronic devices require multiple radio frequency front ends for each antenna array, leading to increased hardware costs and complexity.
Innovation Solution
An antenna structure that allows multiple antenna arrays to share a fewer number of radio frequency components through a radio frequency transfer switch, enabling switching between arrays without the need for one-to-one correspondence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple radio frequency front ends are arranged in one-to-one correspondence with multiple antenna arrays, then each antenna array can be connected with a dedicated radio frequency component, but the number of radio frequency components increases and production cost increases
Solution Approach 1:
A single radio frequency component is designed to serve multiple antenna arrays through a transfer switch, enabling one component to perform multiple functions by dynamically connecting to different antenna arrays as needed
2Reliability
If multiple radio frequency front ends are arranged in one-to-one correspondence with multiple antenna arrays, then each antenna array has dedicated radio frequency support, but device complexity and hardware cost increase
Solution Approach 1:
A transfer switch is introduced as an intermediary component that manages connections between radio frequency components and antenna arrays, allowing dynamic routing and reducing the need for dedicated connections while maintaining system reliability
