Antenna Switching Layout for Flexible External RF Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration of communication devices with a one-to-one relationship between external connecting terminals and communication terminals limits the degree of freedom and complicates assembly, especially as the number of communication terminals, internal antennas, and external antennas increases to support multiple communication systems like 5G.
Innovation Solution
A communication device with a first switch device that connects communication terminals to either internal or external antennas and a second switch device that selects communication terminals to connect to external terminals, controlled by a controller, allowing for increased flexibility and reduced complexity in wiring and substrate requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a one-to-one relationship is maintained between external connecting terminals and communication terminals, then each terminal can be directly connected, but the degree of freedom is limited and assembly becomes complicated
Solution Approach 1:
The external connecting terminal is designed to support multiple communication systems (e.g., 5G, LTE, Wi-Fi) through a single interface. The switch device enables this external terminal to be dynamically connected to different communication terminals based on the required communication system, making the external terminal universal and multi-functional rather than dedicated to a single communication terminal.
Solution Approach 2:
Multiple communication terminals that support different communication systems are merged into a single connection path through the switch device. Instead of providing separate external connecting terminals for each communication terminal, the patent combines them into one shared external terminal that can be switched between different communication terminals, reducing assembly complexity.
2Adaptability or versatility
If the number of communication terminals and external antennas increases to support multiple communication systems, then communication capability is improved, but wiring and substrate requirements increase complexity
Solution Approach 1:
The external connecting terminal serves multiple communication systems (5G, LTE, Wi-Fi, etc.) through a single interface. The switch device enables dynamic allocation of this universal terminal to different communication terminals based on which communication system is currently active, providing multi-system support without proportionally increasing the number of external terminals or wiring complexity.
Solution Approach 2:
The connection between external terminals and communication terminals is made dynamic through the switch device. Instead of fixed one-to-one connections, the switch device dynamically routes signals based on which communication system is in use, allowing the same external terminal to serve different communication systems at different times, thereby reducing static wiring and substrate requirements.
