Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demands of 5G mobile communication networks require more flexible and efficient antenna structures in electronic devices, as traditional antenna arrays with fixed elements fail to adapt to varying communication requirements effectively.
Innovation Solution
The proposed antenna structure incorporates a radio frequency switch that can reconfigure feed ports to connect with different array elements, allowing for the formation of multiple antenna arrays, enhancing flexibility and coverage by shifting the feed object of each feed port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antenna arrays are arranged in an electronic device to meet 5G communication requirements, then communication performance is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic reconfigurability by introducing a radio frequency switch that can dynamically change the connection state between feed ports and array elements. This allows the antenna array to adapt its configuration based on communication requirements, transforming a static complex structure into a dynamic one that can be optimized for different scenarios, thereby improving communication performance without permanently increasing device complexity.
Solution Approach 2:
The patent creates a universal antenna array system where a single set of array elements can serve multiple functions by being reconfigured through the radio frequency switch. The same physical elements can form different antenna arrays for different communication modes, frequencies, or beam directions, replacing the need for multiple dedicated antenna arrays and thus improving performance while reducing overall system complexity.
2Device complexity
If fixed array elements are used in traditional antenna arrays, then device complexity is reduced, but adaptability to varying communication requirements deteriorates
Solution Approach 1:
The patent transforms the static fixed array element configuration into a dynamic reconfigurable system by introducing the radio frequency switch. This switch enables the array elements to be dynamically assigned to different feed ports based on communication requirements, allowing the same physical structure to adapt to varying needs without increasing physical complexity.
Solution Approach 2:
The patent changes the operational parameters of the antenna system by enabling dynamic control over which array elements are activated and how they are connected to feed ports. This parameter reconfiguration allows the system to adapt its electrical characteristics and radiation patterns without changing the physical structure, thereby improving adaptability while maintaining simplicity.
