Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing antenna modules occupy too much space in terminals due to the need for multiple modules to support various frequency bands, limiting the compactness and efficiency of communication devices.
Innovation Solution
An antenna module with a combination of an annular structure and an inverted F structure, utilizing a feeding branch, first branch, second branch, and grounding branch, which allows for operation across multiple frequency bands, reducing the number of modules required and optimizing space usage, while also enabling adjustment of resonant frequency through structural parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antenna modules are configured to support multiple frequency bands, then the radiation performance requirement of MIMO antenna is met, but the occupied space of the terminal increases
Solution Approach 1:
The patent combines multiple antenna elements (first antenna element and second antenna element) into a single antenna module, allowing the module to support multiple frequency bands while occupying less space than separate modules would require
Solution Approach 2:
The antenna module is designed to operate across multiple frequency bands (first frequency band and second frequency band) simultaneously, making it a universal solution that replaces the need for multiple specialized antenna modules
2Volume of moving object
If the number of antenna modules is reduced to save space, then the occupied space decreases, but the ability to support multiple frequency bands may be compromised
Solution Approach 1:
The antenna module is divided into distinct antenna elements (first antenna element with feeding branch and grounding branch, second antenna element) that can be independently configured to support different frequency bands while working together in a compact arrangement
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement of antenna elements and branches, positioning elements at different heights and orientations to achieve multi-frequency operation within a compact footprint, effectively using vertical and lateral dimensions to pack more functionality into less space
