Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently integrating multiple communication functions such as 2G, 3G, 4G, 5G, and NFC, requiring significant space and compromising internal layout due to separate antennas for each function.
Innovation Solution
A shared antenna system is implemented, where communication antennas for 2G, 3G, 4G, and 5G are partially shared, and the NFC antenna is integrated, utilizing a frequency modulation circuit, tuning circuits, and high-frequency suppression circuits to optimize signal radiation and reduce space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate antennas are configured for each communication function (2G, 3G, 4G, 5G, NFC), then each communication function can operate independently and reliably, but the device occupies significant space and compromises internal layout
Solution Approach 1:
The patent combines multiple communication antenna functions into a shared antenna structure. The same antenna is used for 2G, 3G, 4G, and 5G communications, and the NFC antenna is integrated within the device body. This merging approach reduces the total antenna space while maintaining independent operation of each communication function through frequency modulation and signal routing circuits.
Solution Approach 2:
The shared antenna is designed to perform multiple communication functions simultaneously or sequentially. By using frequency modulation circuits and switching mechanisms, a single antenna structure supports 2G, 3G, 4G, and 5G bands, making the antenna universal for multiple purposes and significantly reducing the space required compared to having separate dedicated antennas for each function.
2Area of stationary object
If a shared antenna system is implemented to reduce space, then antenna space is reduced and internal layout is enhanced, but the device complexity increases due to frequency modulation circuits, tuning circuits, and high-frequency suppression circuits
Solution Approach 1:
The patent introduces intermediary circuits including frequency modulation circuits, tuning circuits, and high-frequency suppression circuits as mediators between the shared antenna and multiple communication functions. These intermediary components enable a single antenna to serve multiple purposes by managing signal frequencies and preventing interference, thus reducing antenna space while controlling the increase in device complexity through standardized circuit designs.
