Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the era of 5G communication, terminal devices face challenges in accommodating antenna modules due to space constraints, particularly when aiming for full-screen displays, dual speakers, dual microphones, large battery capacity, and minimal slots, as traditional antenna layouts are inefficient and occupy significant space.
Innovation Solution
The antenna module design incorporates a first radiator and a second radiator with a gap between them, sharing a conductive sheet and using filter networks and impedance matching networks to enable simultaneous reception and transmission of radio signals in different frequency bands, reducing the need for separate radiators and optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional antenna layout technologies are used, then the antenna module can be implemented, but the space occupied by the antenna module is large
Solution Approach 1:
The patent combines multiple radiating elements (first radiator and second radiator) and their feeding structures into a single integrated antenna module. The first and second radiators are positioned adjacent to each other and share common feeding points, merging what would traditionally be separate antenna components into one compact unit, thereby reducing the overall space occupied while maintaining multi-frequency band capabilities
Solution Approach 2:
The antenna module is designed to handle multiple frequency bands (first frequency band and second frequency band) simultaneously through a single structure. The first and second radiators, along with their shared feeding points and grounding structures, enable the module to function across different frequency ranges, eliminating the need for separate antenna modules for each frequency band
2Reliability
If separate radiators are used for different frequency bands, then signal quality is maintained, but the device complexity increases
Solution Approach 1:
The patent merges multiple radiating elements into a single integrated structure where the first radiator and second radiator are positioned adjacent to each other and share common feeding points and grounding structures. This consolidation maintains the ability to handle different frequency bands separately while reducing overall structural complexity compared to using completely separate antenna modules
Solution Approach 2:
Within the integrated antenna module, the radiating elements are segmented into distinct first and second radiators with separate feeding points for different frequency bands. This segmentation allows independent optimization of each frequency band's signal quality while maintaining overall structural integration, balancing complexity reduction with signal quality preservation
